I'm 16 years old, and about 7 months ago i randomly woke up and i forgot what exactly happen but i just got this urgent pain in my right testical. I wasn't sure until 2 months later i found a bump on my testical. But i thought that was part of the attachment to the testical. About 2 months ago is when i relised the testical started to act weird. my left testical is bigger then my right but then one day when i self-examined my testical. It kept going up and down really quickly when i would walk. When i would stop it would settle dow n and be the same size as my other testical. Now when i masterbate i feel this line around my right testical and it hardens really hard. I try to follow it to see exactly what it is but still i have no idea what it is but it feels hard when i get an erection and when my scrotum shrinks.

I need to know what to do. I don't know what to do. I think from reading some forums i have to go to the docter emmidiatly but i dont know what to do when i go there. I need help quickm because i hear this can be really deadly and i'm getting bad thought from it.
