Skin rashes and other itchy irritations can be caused by a number of things, such as allergies, exposure to soap and other substances, and even family history. Below is a guide to some of the most common skin problems and how to treat them. If you have a severe irritation that covers a large area of the body, a rash that is not going away, or if you have other symptoms you should see your healthcare provider.
