Doctor can examine: Rashes are hard to describe in words. Usually, a doctor has to look at a rash to decide on a cause. For common rashes such as eczema, mild reactions to plants or chemicals (such as soap), excess dryness, or little itchy bumps, the doctor may recommend over-the-counter cortisone cream two or three times a day for 1 week. For fungal infections like T. versicolor, selenium products may be needed.
