Answer: Treatment can include external and internal medications for itching and inflammation. Mild inflammation and itching can be relieved with antihistamine drugs or calamine lotion, zinc oxide, or other mild lubricants or anti-itching creams. Gentle, soothing strokes should be used to apply the ointments, since vigorous rubbing may cause the lesions to spread. More severe itching and inflammation is treated with topical steroids. Moderate exposure to sun or ultraviolet light may help heal the lesions, but you should avoid being sunburned.Soap makes the rash more uncomfortable; so you should bathe or shower with plain lukewarm water, use sorbalene instead of soap, and apply a thin coating of bath oil to freshly-dried skin afterwards.
