I seem to have a ball just by the of side of my right testicle, not on or in it, I noticed it quite a while ago but just thought is was a spot as I popped it multiple times. The other day I noticed it again but it was a bigger ball and then the next day it got even bigger and hurt if I squeezed it. Throughout the day it grew much bigger and hurt if I even touched it, and it hurts to even walk properly. It's red, and you can see the lump but it feels like a ball. I'm going to see a doctor soon but was just wondering if anyone else has experienced this or would know what it is as what I have read on the internet, it hasn't affected people to this extent. Any advice or help would be much appreciated.
