Hey, I'm 17 years old and consider myself healthly, the other day after i had a bath, i got out and dried myself off with my towel, and touched the back of my right testicle only slightly where I think the tube leads from my right testicle upward (I think the real name is epyd something), and got a HUGE shooting pain right through the right of my groin. so obviously I though WHAT THE HELL!!!!!!!!!!!, so I touched it again and got the same huge pain, I wasn't touching it at all hard, not even really tapping it to be honest, but it still hurt a LOT!!!. I then did it on the other testicle to see if it did the same, (because I worried) and it didn't do anything, didn't even hurt, I touched it in the same place aswell. it doesn't hurt at all when nothing touches it apart from obviously after it happens when i'm in shock it hurts for about 10 seconds, but then nothing, untill it gets touched by something again. I#m so so so worried about this, I was shaking for about 3 hours after it happened because I was in shock :'( . Can you tell what might be wrong? Please help :'(

Edit: I touched the back of my testicle with the towel REALLY lightly on the back, also it was an accident incase you are wordering why the hell would he be doing that
