Swollen vein around head of penis
A few days ago when I was doing what all of us do when were bored, I felt a very slight pain and looked down to see what looks like a swollen vein, but may not necessarily be a vein, creating a ring just under the head of my penis. It almost forms a complete circle, and definitely feels like it is in or underneath the foreskin (I am circumcised). It doesn't necessarily hurt, but its really strange and I've been taking NSAID's daily to see if its just some kind of swelling, but they don't seem to do much.
Anyone know what this may be? I've looked at all sorts of STD pictures online, and this looks nothing like anything I can find. The closest thing to it was a "varicose vein?"
