Should I see a healthcare provider? The following four rules may help you make that decision. If a rash really bothers you, go see your healthcare provider—period. It doesn't matter whether it's a common skin problem , or whether other people tell you that it's no big deal.

You're the one who has to live with your skin, so if you want to get professional care, do it. Even easily treated rashes can cause an immense amount of physical discomfort if you don't know what to do about them.

Imagine not knowing that you have athlete's foot. You may be able to tolerate the itching and burning skin for a few days or weeks, but you will probably reach a point when it drives you crazy.

The rash isn't contagious or life-threatening, but it can be very uncomfortable. Many substances can cause such reactions, including soaps, cosmetics, fragrances, jewelry and plants.

To treat contact dermatitis successfully, you need to identify and avoid the cause of your reaction. If you can avoid the offending substance, the rash usually clears up in two to four weeks. You can try soothing your skin with cool, wet compresses, anti-itch creams and other self-care steps. Contact dermatitis usually affects areas of skin directly exposed to an offending substance. Here, the dry, red rash is likely caused by cosmetics or soap.

Blisters such as these are common in a skin reaction to urushiol, the highly allergenic oily substance in poison ivy. Contact dermatitis usually occurs on areas of your body that have been directly exposed to the reaction-causing substance — for example, along a calf that brushed against poison ivy or under a watchband. The rash usually develops within minutes to hours of exposure and can last two to four weeks.

Contact dermatitis is caused by a substance you're exposed to that irritates your skin or triggers an allergic reaction. The substance could be one of thousands of known allergens and irritants. Some of these substances may cause both irritant contact dermatitis and allergic contact dermatitis. Irritant contact dermatitis is the most common type. This nonallergic skin reaction occurs when a substance damages your skin's outer protective layer.

Some people react to strong irritants after a single exposure. Others may develop signs and symptoms after repeated exposures to even mild irritants. In this blog we will focus on the three main types of skin rashes associated with COVID: urticaria hives , erythemato-papular rash described as a red bumpy rash or erythemato-vesicular rash described as chicken pox-like rash , and chilblains.

These rashes can present quite early on in the infection, but can also last a long time after, when the patient is no longer contagious. The rash appears as sudden raised wheals on the skin which come and go quite quickly over hours and are usually very itchy.

It can involve any part of the body. If it affects the face, it can cause swelling of the lips and eyelids. The eruption can also start with intense itching of the palms or soles. It is usually treated with antihistamines. If the patient has lip swelling, it is important to check that there is no difficulty in breathing or wheezing as this would need urgent medical attention.

An erythemato-papular rash described as a red bumpy rash or erythemato-vesicular rash described as chicken pox-like rash rash is different from urticaria as it persists for days or weeks. It appears as red and bumpy areas which may occur anywhere on the body, but favours the elbows and knees as well as the back of the hands and feet.

It can resemble bad prickly heat. In some cases, it is only tiny bumps all over the skin and the signs may be more subtle. This is also usually very itchy. The rash can also last well after the contagious stage is over and may also appear many weeks after the onset of the infection.

It is known as chilblains and was relatively rare before COVID as it was seen mainly during cold spells and in people who had some problems with circulation in the fingers or toes. At the outset of COVID, however, dermatologists started to notice this type of rash much more than normal and in warm weather which seemed very unusual.

The rash presents itself as reddish and purplish bumps on the fingers or toes and can affect many digits. This type of rash is usually present later in the infection and again may appear weeks after the onset of the viral infection. The fingers and toes are usually sore, but not itchy. When the rash recovers, the top layers of the skin may peel where the purplish bumps were. COVID can also cause sore and watery eyes. The lips may also feel sore and may be dry and scaly when they recover. Soreness inside the mouth can also occur.

Our research has been published in leading medical journal, Nature, today. It often improves over time, although it can last into adulthood or start later in life. In this condition, the water-tight barrier between skin cells gets weak, which lets moisture out and other things in. Researchers have recently identified specific genes Stretches of DNA, a substance you inherit from your parents, that define characteristics such as how likely you are to get certain diseases.

People with certain versions of these genes are more likely to get atopic dermatitis. A skin allergy, or allergic contact dermatitis, produces a red, itchy rash that sometimes comes with small blisters or bumps. The rash arises when the skin comes in contact with an allergen, a usually harmless substance that the immune system attacks. Allergens trigger allergic reactions. Allergens can come from certain soaps, creams and even pets. Your immune system might not react the first time you encounter an allergen.

But over time, your immune system can become sensitive to the substance. As a result, your next contact may lead to inflammation and an allergic rash. Because of ear piercing. Other common causes of allergic dermatitis are poison oak and poison ivy.

If you touch one of them, wash your skin as soon as possible. Mild cases of allergic contact dermatitis usually disappear after a few days or weeks.
