question: I have a rash on my back that begins with small red dots, becomes itchy and then crusts over with a scab. The dots turn brown after that. My internist diagnosed folliculitis. I have used bactroban, levaquin, Tinactin, and Triamcinolon to no avail. It is not spreading anywhere. I have a past history of Lichen planus. I cannot get into the dermatologist I saw in the past, as I had no need to see him the past six years.
