Testicular Torsion
Lads, if you haven't had it, you might be in for a real treat one day, so picture this - one, or both, of your balls managed to rotate around its axis, slowly cutting off its own blood supply and strangling itself halfway to death. Now imagine that it did this on and off for a month until one day it stopped doing a half-arsed job of it and went for the full turn, wrenching the pain dial up to 11. Once diagnosed you have about a six hour window to have surgery before your testicle(s) start to die inside you taking all (or half!) your swimmers along with it / them.

That was quite bad. Though I have to say the recovery was also not pleasant, and the repeat operation three years later for an infection grown into the original site was about the least comfortable thing to endure to date, worse than a broken radius or the aftermath of four teeth being pulled.

My orthodontic treatment
involved having four teeth pulled. That part was easy, first two months of braces were very uncomfortable. Chewing anything was a challenge and could be very painful.

I couldn't handle anything going wrong with my balls though.. You have my sympathies.
