Skin rashes: Types, Causes, Diagnosis, Treatment

A rash is a part of skin that appears to be different than the rest of your skin around it. It may be red and/or swollen. It may also feel itchy. A skin rash is fairly common and can happen to anyone. However, it is very important to be able to distinguish the kind of rash to address the root cause.

Different rashes have different symptoms. In fact, some types of skin rash may even make your skin turn purple or grey. A skin rash can be annoying and uncomfortable, but many times they go away on their own or with simple treatments. Health Shots got in touch with dermatologist Dr Priyanka Kuri to know all about skin rashes, their causes and cure.

A skin rash is when your skin looks or feels different than usual. It can make your skin appear red, swollen, and bumpy.

Some rashes are small and localized, while others can cover larger areas of your body,” says Dr Kuri. If a rash persists or gets worse, it’s a good idea to see a doctor.
