What is a skin rash?

A skin rash is an inflammation of the top layer of your skin or mucous membrane. There are various causes of skin rashes, such as allergies and infections. There are also many different types of skin rashes, and in this post, we will look at ten of the most common.

1. Eczema

You stand a higher chance of suffering from eczema if your family has a history of allergies or asthma. Medical experts aren’t clear on what exactly is responsible for eczema. Some believe it is your immune system’s response to something irritating.

  • Heat

How is Eczema diagnosed?

Finding eczema isn’t restricted to one procedure. Some doctors may diagnose you by only looking at your skin and probing you with a few questions. Other doctors may order you to take some allergy tests. This is because many people with eczema also suffer from allergies. Therefore, the allergy test will check for irritants.
