question: Hi, may I answer your health queries right now ?  Please type your query here...about 2 months ago I found what I thought was a mosquito bite on my pubic area. As it turns out, a few more popped out and formed a ring/ semicircle. It is painfully itchy. Today, I noticed that it is white and scaly in appearance. Can it be treated with otc meds or do I need a script?Thanks
