I have a rash on my left side of my stomach ?

Doctor can examine: Rashes are hard to describe in words. Usually, a doctor has to look at a rash to see what it might be. For common rashes such as eczema, mild reactions to plants or chemicals, excessive dryness, or little itchy bumps, over-the-counter Hydrocortisone 1% cream usually helps. A rash of tiny blister-like bumps, on one part of the body, can be shingles, especially if the rash is painful.
