About a few months ago I noticed a weird skin mark developed on my inner thigh region out of nowhere. This mark resembles a stretch mark, but it's slightly dented, and a lot more wrinkly. When I stretch it out you can see veins in the dent, and its a slightly purplish color. Every now and then it'll hurt a little bit. It's more of a tugging pain. It is located on my thigh very close to my testicles, and every now and then I'll notice my testicles will hurt a little bit too for no reason, which I'm not sure if it is related to the skin mark or not. Anyone know what this could be? I want to get it checked out by a doctor but I just can't afford it right now.
