I have a bump the size of a a dime on my arm . It s more so raised skin, not formed like a big bump, redish. I squeezed it earlier clear liquid came out of all the pores, not just one opening. There were some small white heads forming around it, I though it might be ring worm (I coach wrestling). I put lotrimin on it and the white heads disappeared. The skin it still hard and raised, filled with this clear puss. Should I continue to use Lotrim, and clean it with alcohol, or see a doctor?
