Hello, To whoever may read this, I have had a problem with poison ivy. I guess i beleived it to be a mosquito bite at first, so i scratched it. It spread to my penis, most specifically the underside and from the circumcision scar to the base of the head. Right now, I'm am using a antihistamine/ analgestic cream to rid of it, and it is almost hone. However, the sink on the underside of my penis is completely dry, and has dark red patches of skin near the top. I was wondering, is this serious, or will it eventually go away?
