Hey, I'm a 17(18 in 9 days) year old male. So I noticed yesterday after a nap that my right testicle hurt, with about the same pain as if I had recently been sacked. Then a few hours later it seemed as if my testicle was getting larger, as I felt pressure. I thought a warm bath might fix it, but during the bath I noticed that there is either a large lump on my testicle, or it somehow split in half. I have not recently sustained any testicular injury, so I'm a tad confused.
Could it be testicular cancer?
