About 2 weeks ago i had 2 small bumps appear on the shaft of my penis. they apeared completely overnight. within 2-3 days one of the bumps peeled and disappeared completely but the larger one is still present. It has since had a layer peel off almost like a scab and is now flat. The pink mark seems to be getting smaller. Initially i was scared it could be genital warts but I couldnt find any information on them appearing overnight and then shrinking in size. Everything I read seems to say that they get larger gradually - not overnight then shrink. I have also had an itchy feeling that comes and goes on different parts of my penis. The itching is mostly on the underside of my penis while the bumps are on the upperside. It also appears that a hair follicle bump is at the center of the pink mark. Could it just be a follice that got infected? Any help would be appreciated because I am very worried.
