Skin Untitled Document Hives and heat rash are two of the most common rashes. In most cases, these conditions can be treated at home.
Hives are an allergic reaction to food or medication.
They are either small, red bumps or itchy, welt-like areas. Stop eating the food or using the medicine that may be causing the rash, and talk to your doctor about it. If you get hives often, ask your doctor to recommend an antihistamine to relieve the itchiness. For temporary relief from itching, apply witch hazel or rubbing alcohol, bathe in lukewarm water and baking soda, or apply calamine lotion. While it sounds hard to believe, you may get heat rash during the summer or winter.
