Skin Rash

Edited by Dr Claudia Pastides, 25th April 2019

Developing a skin rash can be a worrying time - especially if you’re not sure what’s caused it. There are hundreds of possible reasons why you may have developed a rash. It’s always best to have a rash looked at by a medical professional, who will be able to diagnose the problem and advise on the best possible course of treatment, if needed.


A skin rash is usually red and itchy, and can occur anywhere on the body. Sometimes it may be accompanied by cracked, sore skin or red lumps on the surface. A rash is often the sign of a skin condition or can be a symptom of other illnesses. If you’re worried about a rash, especially on a child, it’s always best to get it checked out by a GP. Most of the time an accurate diagnosis can be made just by looking at the rash, so you can book a video consultation from home

Causes of rashes

There are many reasons why you might see a rash appearing on your body. Many rashes are caused by common skin conditions, which can include:

You can also develop a rash as a result of an allergic reaction, or overexposure to heat. In some cases, rashes can be a sign of an underlying condition, such as shingles, chickenpox, meningococcal disease or toxic shock syndrome. These illnesses will often be accompanied by other symptoms as well as a rash. If you’re experiencing other symptoms as well as a rash, speak to a medical professional immediately.

Treating a rash

Treatment for any rash will depend on the diagnosis. Some rashes, such as eczema, ringworm or psoriasis, can be treated with a cream or other topical solution. Many of these will be available over-the-counter at a pharmacy. Other rashes may need to be treated with a course of antibiotics - this will require a prescription, which can be provided by our team. Certain rashes need no treatment at all, and will go away on their own. Speak to a doctor today to have your rash diagnosed and discuss the best possible course of treatment for you.
