My right testicle really hurts, and it's hurt for about 2 months now. I just learned how to do a TSE a while ago, and did one now. On the bottom when i touch it, I'm not sure if I feel a lump or not, but it hurts so bad I don't want to continue doing it. I rubbed it a little to see if it is a bump, but really I can't tell... All I know is that it just hurts really really bad when I touch that spot.
