So I've got this itchy kind of mosquito bite sized lump on the shaft of my penis, on the left about mid-way up. It's not attached to the muscle, just on the skin, and it's itchy as hell. Been there for about 4 days now and shows no sign of going down. I'm not sexually active so can't think of what it could be. Any ideas?
It could be a pimple, you can get them on your penis, or possibly a sebaceous cyst, a clogged oil gland.
Warm compresses should help reduce the swelling.
It should go away in a few days. If not, see your doctor. It is NOT an indicator of an STD.
Hope it helps.
