So I woke up 2 days ago with a non-stop pain in my left testicle, this has happened before and I had to wait it off for about 3 hours and it stopped, so I tried that, it didn't help. So I decided to sleep it off, and in the morning, I went to the bathroom (I was STILL in pain) and from what it looked like, it was my sperm cord on top of my testicle and it was swollen, so I decided to go to the doctors today and guess what? It turns out I have something called testicular torsion. The doctor said it happened in my sleep and my testicle turned 360 degrees and wrapped around the cord. Tonight, at 7:00 PM, I have to have surgery, I am typing this now in a hospital bed.
MORAL: Be careful when you sleep on your side or stomach, the worst could happen.
