Contact dermatitis
Contact dermatitis is one of the most common causes of rashes. This type of rash occurs when the skin comes into direct contact with a foreign substance that causes an adverse reaction, leading to a rash. The resulting rash may be itchy, red, or inflamed.
Possible causes of contact dermatitis include:
- beauty products
- soaps
- laundry detergent
- dyes in clothing
- chemicals in rubber, elastic, or latex
- poisonous plants, such as poison oak, poison ivy, or poison sumac
Medications
Taking medications may also cause rashes. They can form as a result of:
- an allergic reaction to the medication
- a side effect of the medication
- photosensitivity from the medication
Other causes
Other possible causes of rashes include the following:
- A rash can sometimes develop in the area of a bug bite, such as a fleabite. Tick bites are of particular concern because they can transmit disease.
- Atopic dermatitis, the most common form of eczema, is a rash that may be more common in people with asthma or allergies. The rash is often reddish, though it can be skin-colored or darker on people with darker skin tones. It can be itchy with a scaly texture.
- Psoriasis is a common skin condition that can cause a scaly, itchy, red, or purplish rash to form along the scalp, elbows, and joints.
- Seborrheic eczema is a type of eczema that most often affects the scalp and causes redness, scaly patches, and dandruff. It can also occur on the ears, brows, or nose. When babies have it, it’s known as cradle cap.
- Systemic lupus erythematosus is an autoimmune disease that can trigger a rash on the cheeks and nose. This rash is known as a “butterfly,” or malar, rash.
- Rosacea is a chronic skin condition of unknown cause. There are several types of rosacea, but all are characterized by redness and rash on the face.
- Ringworm is a fungal infection that causes a distinctive ring-shaped rash. The same fungus that causes ringworm on the body and the scalp also causes jock itch and athlete’s foot.
- Diaper rash is a common skin irritation in infants and toddlers. It can be associated with prolonged exposure to a wet diaper.
- Scabies is an infestation by tiny mites that live on and burrow into your skin. It causes a bumpy, itchy rash.
- Cellulitis is a bacterial infection of the skin. It usually appears as a red, swollen area that is painful and tender to the touch. If left untreated, the infection causing the cellulitis can spread and become life threatening.
Causes of rashes in children
Children are particularly prone to rashes that develop as a result of illnesses:
- Chickenpox is caused by a virus, and the rash is characterized by small itchy bumps and blisters that form all over the body.
- Measles is a viral respiratory infection that causes a widespread rash consisting of itchy, red bumps.
- Scarlet fever is an infection due to group A Streptococcus bacteria that produces a toxin, causing a bright red or skin-tone-colored, sandpaper-like rash.
- Hand, foot, and mouth disease is a viral infection that can cause red lesions on the mouth and a rash on the hands and feet.
- Fifth disease is a viral infection that causes a red, flat rash on the torso, arms, and legs.
- Kawasaki disease is a rare but serious illness that triggers a rash and fever in the early stages and can lead to heart complications.
- Impetigo is a contagious bacterial infection that causes an itchy, crusty rash and yellow, fluid-filled sores on the affected area, such as the face, neck, or hands.
You can treat most contact rashes, but it depends on the cause. Follow these guidelines to help ease discomfort and speed up the healing process:
- Use mild, gentle cleansers instead of scented bar soaps.
- Use warm water instead of hot water for washing your skin and hair.
- Pat the rash dry instead of rubbing it.
- Let the rash breathe. If it’s possible, avoid covering it with clothing.
- Stop using new cosmetics or lotions that may have triggered the rash.
- Apply unscented moisturizing lotion to areas affected by eczema.
- Avoid scratching the rash because doing so can make it worse and could lead to infection.
- Apply an over-the-counter (OTC) hydrocortisone cream to the affected area if the rash is very itchy and causing discomfort. Calamine lotion can also help relieve rashes from chickenpox, poison ivy, or poison oak.
- Take an oatmeal bath. This can soothe the itchiness associated with rashes from eczema or psoriasis. Here’s how to make an oatmeal bath.
- Wash your hair and scalp regularly with dandruff shampoo if you have dandruff along with a rash. Medicated dandruff shampoo is commonly available at drugstores, but your doctor can prescribe stronger types if you need them.
Over-the-counter (OTC) medications
Talk with a healthcare professional, who may recommend OTC medication like ibuprofen or acetaminophen to treat mild pain associated with the rash.
Avoid taking these medications for an extended period because they can have side effects. Ask a healthcare professional how long it’s safe for you to take them. You may not be able to take them if you have liver or kidney disease or a history of stomach ulcers.
Call a healthcare professional if the rash doesn’t go away with home remedies. You should also contact them if you’re experiencing other symptoms in addition to your rash and you suspect you have an illness.
If you don’t already have a physician, you can use the Healthline FindCare tool to find a professional near you.
Go to the hospital immediately if you experience a rash along with any of the following symptoms:
- increasing pain or discoloration in the rash area
- tightness or itchiness in the throat
- difficulty breathing
- swelling of the face or limbs
- fever of 100. 4°F (38°C) or higher
- confusion
- dizziness
- severe head or neck pain
- repeated vomiting or diarrhea
Contact a healthcare professional if you have a rash as well as other systemic symptoms, including:
- joint pain
- a sore throat
- red streaks or tender areas near the rash
- a recent tick bite or animal bite
Your healthcare professional will perform a physical exam and inspect your rash. Expect to answer questions about your:
- rash
- medical history
- diet
- recent use of products or medications
- hygiene
Your healthcare professional may also:
- take your temperature
- order tests, such as an allergy test or complete blood count
- perform a skin biopsy, which involves taking a small sample of skin tissue for analysis
- refer you to a specialist, such as a dermatologist, for further evaluation
Your healthcare professional may also prescribe medication or medicated lotion to relieve your rash. Most people can treat their rashes effectively with medical treatments and home care.
Follow these tips if you have a rash:
- Use home remedies to soothe mild contact rashes.
- Identify potential triggers for the rash and avoid them as much as possible.
- Call a healthcare professional if the rash doesn’t go away with home treatments. You should also contact them if you’re experiencing other symptoms in addition to your rash and you suspect you have an illness.
- Carefully follow any treatments your doctor prescribes. Speak with a healthcare professional if your rash persists or gets worse despite treatment.

Rash on Hands and Feet: Common Causes and Treatment
Rashes are earmarked by a change in the color and texture of your skin. They may have blisters, and they may itch or hurt. Rashes that break out on your hands and feet have a wide range of underlying causes.
We’ll explore some of the common conditions that cause rashes to occur on the hands and feet. We’ll also look at treatment options you can try at home, or under a doctor’s care.
Common causes of rashes on the hands and feet | Overview |
hand, foot, and mouth disease | contagious infection caused by several viruses, including the coxsackie virus |
granuloma annulare | chronic, degenerative skin condition with an unknown cause |
dyshidrotic eczema (dyshidrosis, pompholyx) | itchy, common form of eczema |
impetigo | contagious, bacterial skin infection |
hand-foot syndrome (acral erythema or palmar-plantar erythrodysesthesia) | side effect of certain chemotherapy drugs |
athlete’s foot | contagious fungal infection |
Rashes on the hands and feet can be caused by environmental factors, such as irritants or allergens. They may also be the result of medical conditions or infections.
Some common causes of rashes on hands and feet include:
Hand, foot, and mouth diseas
eHand, foot, and mouth disease is a contagious infection caused by several viruses, including the coxsackie virus. Anyone can get hand, foot, and mouth disease, although it most commonly occurs in babies and children.
This condition causes a rash on the hands and feet, as well as sores in the mouth and on the tongue. You may experience fever and a sore throat with this condition.
The hand and foot rash caused by this condition sometimes causes blistering to occur, and may be painful, but not itchy. In some instances, it may appear on the buttocks, as well.
Granuloma annulareGranuloma annulare is a chronic, degenerative skin condition with an unknown cause. There are five recognized types:
- localized granuloma annulare
- generalized or disseminated granuloma annulare
- subcutaneous granuloma annulare
- perforating granuloma annulare
- linear granuloma
The most common type, localized granuloma annulare, causes rings of flesh-toned, red, or yellow nodules to form on the feet, hands and fingers.
These nodules are small and hard, but do not typically itch. The rings usually clear up on their own without treatment, within a few months to two years. They may, however, come back.
Granuloma annulare is more common in women than in men, and tends to occur during young adulthood.
Dyshidrotic eczema (dyshidrosis, pompholyx)
This very itchy, common form of eczema causes deep-set blisters on the palms of hands, edges of fingers, soles and sides of feet, and toes. The blisters can become large and painful, and may last for several weeks.
Dyshidrotic eczema outbreaks often coincide with seasonal allergies, during spring and summer. It’s more common in women than in men. This condition is not curable, but its symptoms can be successfully treated. It’s not contagious.
Impetigo
This very contagious, bacterial skin infection begins with an oozing rash of red sores around the mouth and nose that can be spread to the hands and feet via touch. When the sores burst, they develop brownish-yellow crusts.
The rash can be itchy, and painful. Impetigo most commonly occurs in infants and children. Itching and soreness are other symptoms.
Hand-foot syndrome (acral erythema or palmar-plantar erythrodysesthesia)
This condition is a side effect of certain chemotherapy drugs used for cancer treatment. It’s earmarked by pain, swelling, and redness in either or both the palms of the hands and soles of the feet. It can also cause tingling, burning, and blisters. In severe cases, deeply cracked skin and extreme pain may occur.
Athlete’s foot
Athlete’s foot is caused by a contagious fungal infection. It usually starts between the toes, and spreads to the entire foot. This condition is earmarked by a scaly, red rash that itches.
In some instances, athlete’s foot can spread to the hands. This is more likely to happen if you pick at or scratch the rash on your feet.
Athlete’s foot is caused by keeping very sweaty feet trapped in shoes. It can also be transmitted on locker room and shower floors.
Many hand and foot rashes can be treated at home, but some require medical treatment, based on their underlying cause and severity.
There are a number of over-the-counter and at-home rash treatments that may help alleviate itching and pain, plus reduce the appearance of the rash. You may have the best success by combining several.
Home treatments include:
- topical application of over-the-counter hydrocortisone cream
- topical application of anti-itch medications containing pramoxine
- topical application of lidocaine, or other types of pain medication
- cold compresses
- oral antihistamines
- oral pain medication, such as acetaminophen or ibuprofen
- cool oatmeal baths
- applying unscented moisturizing cream
- avoiding triggers, such as pollen
If you have dyshidrotic eczema: Avoid cobalt and nickel in food and in everyday items. Foods that contain cobalt include clams, fish, and leafy green vegetables. Foods that contain nickel include chocolate, soy beans, and oatmeal.
If you have impetigo: Cleaning and soaking the blisters and removing the crusts every few days may help. Cover the area with an antibiotic cream and loose dressing after treating.
If your rash does not clear up, your doctor may recommend the following:
- corticosteroid injections
- liquid nitrogen, applied directly to the rash to freeze the area and remove lesions
- oral medication to reduce immune system reactions
- light therapy using a laser
- blister draining
- antibiotics, if infection occurs
Any rash that’s painful, accompanied by fever, or looks infected should be seen by a doctor. You should also seek medical attention for a rash that doesn’t clear up easily with treatments you use at home.
Your doctor may be able to diagnose the rash visually after taking an oral history. In some instances, you may also expect diagnostic tests, such as:
- skin culture
- allergy tests
- skin lesion biopsy
If your child has a rash that does not clear up within one or two days, they should be seen by their pediatrician. This will help determine the cause of the rash, and provide relief for their symptoms.
If your child has sores in their mouth or throat that prohibit them from drinking, they should also be seen by their doctor, to avoid complications such as dehydration.
Since conditions such as hand, foot, and mouth disease and impetigo are contagious, make sure to wash your hands after caring for your child.
If you’re a cancer patient experiencing hand-foot syndrome, let your doctor know. Your doctor may be able to change the dosage or type of medication you’re taking.
Rashes on the hands and feet can be caused by a wide range of conditions. These types of rashes sometimes clear up on their own, or they are treated easily at home.
Depending on their underlying conditions, some rashes will respond better to treatments performed or prescribed by a doctor. See your healthcare provider for any rash that’s accompanied by fever or pain.

Red dots on the skin: causes, symptoms, care
Below are some of the various etiological factors for the appearance of red dots on the body.
Heat rash (prickly heat)
Obstruction of the sweat glands causes accumulation of sweat in the deep layers of the skin, which provokes the occurrence of prickly heat. This condition mostly affects young children who have underdeveloped sweat glands. The favorite places for the localization of a barely noticeable heat rash are the back, groin, chest, armpits, skin of the hands - the places of the most abundant accumulation of sweat deposits.
Thermal rash may include the following symptoms:
- The totality of papules in the form of small tubercles
- itching and stabbing sensations
- of the skin of
- Monitoring violation
- Halu
- Nausea
As a rule, prickly heat goes away on its own after 24 hours. To improve the condition of the skin, cooling home remedies (compresses, baths) are suitable, as well as preventive measures (wearing loose clothing made from natural fabrics). If a secondary infection has joined, it is necessary to prescribe a course of antibiotic therapy.
Keratosis pilaris
Keratosis pilaris (pilaris) is a common skin condition that presents as small white and red bumps on the surface of the skin. In most cases, the outer part of the shoulders, forearms and upper back are affected.
Symptoms of keratosis pilaris:
- Dryness and roughness of the skin
- Presence of itching
Contact dermatitis
When the skin comes into contact with an allergen, an allergic reaction develops, which leads to contact dermatitis. Manifestations of contact dermatitis can be different depending on the trigger factor.
Symptoms of contact dermatitis include:
➤ Rashes that look like patterns
➤ Presence of peeling, cracks and dryness
➤ Hyperemia of the skin
➤0003
➤ Scarring of the skin
➤ Red color of the skin
➤ Presence of blisters with a crust
➤ Increased sensitivity to sunlight
In care, use products without the presence of aggressive components in the composition, wear jewelry made of natural metals. If large areas of the skin are affected, it is necessary to apply 1% hydrocortisone cream, complicated forms are treated with systemic antihistamines.
Atopic dermatitis
Atopic dermatitis (eczema) is a chronic inflammatory skin disease. There are several types of eczema - follicular and papular.
Manifestations of eczema include:
- Redness and swelling of the skin
- Dryness and flaking of the skin after heavy scratching
- Blisters, followed by the release of fluid and the formation of a crust.
Therapy of atopic dermatitis is based on taking antihistamine drugs, moisturizing the skin, and using phototherapy.
Rosacea
Rosacea is a condition in which the skin becomes covered with small rashes and redness without itching. This pathology is more typical for fair-skinned people aged 30-50 years with a photosensitive skin type.
Symptoms of rosacea:
- Redness of the skin in the nose, forehead, cheeks and chin
- Visible blood network and subcutaneous spots on the face
- Thickening of the skin
- Redness and tearing0034
- Presence of bumps and pimples
To relieve rosacea, it is necessary to moisturize the skin, use pH-balanced cleansers and creams with SPF protection before going out, minimize exposure to precipitating factors (UV light, harsh chemicals), limit consumption of spicy and hot food. As a drug treatment, azelaic acid, metronidazole, brimonidine tartrate are used.
Effective therapeutic and prophylactic remedies for rosacea and rosacea0104
Infections
Red spots on the skin may appear due to the following infectious diseases:
Chicken pox or shingles . The herpes virus that causes these diseases provokes the appearance of red itchy sores with localization throughout the body. Chickenpox usually occurs in infants and preschool children. Shingles affects adults and is characterized by a unilateral rash.
Rubella . Small bright red and pink dots on the skin are manifestations of rubella. The rashes are contagious and are localized mainly on the face, arms, legs and torso. Additional manifestations of rubella include lymphadenitis, fever, headache.
Meningitis . This disease is characterized by inflammation of the meninges and presents with a variety of symptoms, including headache, fever, neck stiffness, and, rarely, a microscopic single rash of red or brown small solitary lesions.
Scarlet fever . The causative agent is streptococcus, which causes red, rough specks in the neck, groin, and armpits.
Cherry angioma
A benign skin neoplasm of small size, resembling a burgundy spot, is called cherry angioma or capillary hemangioma. The shape of the tubercles can be varied, rashes are more typical for people over 30 years old. Angiomas are common on the trunk, arms and legs, and are similar to moles. Over time, they go away on their own and do not require treatment, but if desired, they can be removed with liquid nitrogen or a laser. Angiomas in the form of red droplets do not itch, sometimes they bleed, but this is a variant of the norm.
Ringworm
Mottled, red, raised, rounded dots are the result of ringworm (a fungal infection of the skin). Spots can be on any part of the skin, but most often they are on the arms and legs. The fungus is carried by both humans and pets. The rash is usually accompanied by flaking. Therapy for ringworm is the use of antifungal creams or drugs.
Lichen planus
This disease has an autoimmune course and is characterized by the appearance of flat red purple spots that itch. Lichen planus occurs among females aged 35 to 60 years. It can often be found on the nails, genitals, throat, digestive tract, and even the inside of the mouth. In some cases, the disease goes away on its own. To get rid of lichen planus, it is necessary to use oral antihistamines and topical retinoids.
Red drug rash
Some medications may cause a red rash. Such rashes occur in the form of blisters or hives and are characterized by varying degrees of severity. If a drug allergic reaction is suspected, the drug should be stopped immediately. If the condition remains severe, antihistamines or steroids should be given.
Purpura
Since blood accumulates in the layers of the skin due to the fact that the vessels burst, red dots of different diameters form under the skin, which can even be observed in the oral cavity. In the presence of such ruby points, an immediate consultation with the attending physician is necessary. In simple cases, red vascular dots on the skin are treated with steroids, and platelet levels are also normalized.
Swimmer's itch
A bumpy red rash that occurs after swimming in a body of water infected with schistosomes (parasites of the genus trematodes) is called swimmer's itch or cercarial dermatitis. As a rule, the rash appears during the day and is not transmitted to others. For treatment, antihistamines and steroids are used, in complicated cases, antibiotics.
Psoriasis
Psoriasis is considered an autoimmune disease and occurs against the background of exposure to a trigger factor (stress, infection). The rash is crimson itchy lesions with silvery plaques, localized mainly on the elbows and knees. For the treatment of psoriasis, cold compresses, topical steroids, immunosuppressants are used.
Petechiae
Petechiae are located on the arms, abdomen, legs and buttocks and very much resemble red capillary dots.
