Hi Thanks for your query. Whether it is eczema, chicken pox or itchy skin, if you are dealing with some sort of rash, you need fast relief from the misery. Skin rashes can be uncomfortable and even embarrassing sometimes. We understand that and after proper examination, a dermatologist can help you get that relief. Most rashes are from one source: dermatitis. Dermatitis is a condition that occurs when your skin comes in contact with things that you are allergic to, or things that irritate your skin. Dermatitis causes your skin to become inflamed, which usually leads to a rash. Most rashes are itchy, they cause your skin to be dry, and they make your skin look red and irritated. Depending upon the reason for your rash, your dermatologist will be able to decide on the treatment whether you will respond best to topical treatment or removal of any chemicals or other drugs that you might be using.
