I have a unknown swollen pimple on my penis.? - pimple on shaft swell

I had what I thought was a pimple on the shaft of my penis, then put it on. Like a normal grain, pus, and head. But I noticed that one minutes later it was swelling. I left him alone for a day and the next morning woke up and reduces inflammation. Who knows why or what that is?
