I have tiny flesh colored rashes on my forearms. they look like goosebumps. also dry circular patches of dry skin. what could it be?

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. Itchy bumps on many body parts might be an allergic reaction to something or from other causes.
