I'm 18 years old and I'm experiencing low-abdominal pain and testicular pain when I get up/sit down, when urinating, and other things along those lines. I do not have any swelling of testes, bumps or strange discharge, urinating blood, etc. It is not incredible pain, but it is very unpleasant, mostly during urination. The pain has been present for the last 2 days, and about 2 days ago, I went for a run through some hills, which I usually do not do. I've had testicular problems from running before, simply from my testicles getting knocked around, but this has lasted much longer than before, and this is the first time that it has hurt during urination. A huge thank you to anyone who can offer direction as to what this is, or what could be happening!
