Back when I was 11, I woke up one morning (this was the summer of '06) and as soon as I turned to my other side from my bed, excruciating pain began. I screamed, and I was lucky my parents weren't home. I could barely move. I managed to get out of bed, and realized where the pain began from. I had extreme testicular pain. I went to bed just fine the night before, but somehow woke up with this. I was too scared to tell my parents, because it was a tiny bit embarrassing. Later that day, it went away. I was just wondering if anyone else had something similar, to tell me exactly what it was.
For those who are interested, it was the vein that connected to it that hurt.
