Hello. I m Dr. Christensen. It isn t possible to diagnose your condition without an examination, but a couple of thoughts come to mind: You may be dealing with a condition known as pityriasis rosea. This is a transient, non-contagious rash that often erupts spontaneously but sometimes occurs after a mild viral illness. Pityriasis rosea usually starts as a slightly scaly, reddened patch (the herald patch ) on the chest, abdomen or back. This is followed by clusters of smaller spots erupting across the trunk, neck and upper arms and legs. Pityriasis rosea usually goes away on its own within 6 to 8 weeks, but it lasts for months in some individuals. While it doesn t adversely affect your health, itching is sometimes a problem; this can usually be addressed with oral antihistamines, such as diphenhydramine (Benadryl) or cetirizine (Zyrtec). Another possibility is tinea versicolor, which is caused by a superficial fungal infection of your skin. This is another condition that doesn t affect your overall health, but it can be unsightly and cause mild itching. Tinea versicolor usually responds to topical applications of selenium compounds (e.g., Selsun Blue shampoo), ketoconazole, ciclopirox or zinc pyrithione. Widespread tinea versicolor can be treated with oral antifungal medications (fluconazole, itraconazole or ketoconazole). Since skin disorders cannot be identified without an examination, it would be prudent to have your doctor take a look. Once a diagnosis is made, you can begin treatment if you so choose. I hope that answers your question. Good luck!
