I have been practicing the jelq for a few weeks now and I think I had a prolonged session this last time. I also applied more pressure than usual. After I was done with it in the shower and was gonna warm down, I noticed on the right side of the penis head right below the mushroom swelling. It is about a half inch almost like a worm underneath the skin. I thought that maybe it's just temporary swelling and massaging it would make it go away but it's the third day and it is still there. The swelling hasn't become bigger or smaller it's just there. Do I need to be worried or will this go away on it's own. Thank you.
