Suggest Treatment For Folliculitis

I think that I may have Folliculitis. I have been getting a pimple like rash on my legs after I shave. Usually occurs around the inner and back sides of my upper thighs, but recently I've been getting them all over my legs. They are often painful and are around a hair follical. I stopped shaving for a little while, and still got a few of them. Also, I want to be able to wear shorts and dresses without being embarrassed by this.. how do I stop it. How can I be sure that is actually Folliculitis? Help!
