I've got a hard bump on my shaft under the skin

Alright im back guys. I haven’t been on here for a while so I guess I have a few unanswered questions. A few days ago I noticed a bump under the foreskin right under the head. I’ve been doing some jelging and I’m wanting to know if doing that would cause some build up like a cyst? I don’t know if it is possible to get cancer cells on the shaft but I wouldn’t see why not. Opinions?

Are you paranoid? The third testicle and now a bump? How big is it?

I know right..

If I had to explain the size I’d say it’s like maybe 1/8th inch wide and about 1/2 inch long. I heard like when it comes to checking for testicular cancer, if you shine a light thru the area and don’t see any dark spot you’re most likely okay. So I did that thru my shaft and didn’t see any dark spots. I have a feeling it’s from jelging to hard.

Bump on my shaft.

I found that link. That’s pretty much what I feel. I will probably take some time from exercises. Don’t want to worsen the problem.
