Hi all, I've been itching all over my body real bad for about 2-3 weeks. I went to see my doctor who said it was folliculitis and prescribed me ethromycin. I've took them for 2 weeks and the itching hasn't got any better and I've noticed a few red pimples on the shaft of my penis that are also very itchy. I'm a 22 year old and sexually active. Any ideas what this could be?
