I'm 15, and have been experiencing pain in one testi for the past 2 year, on and off, and it's only now that I've decided to check on it, as it's bugging me. Every time I sit down or pulll my legs up, it feel so like my boxers are pressing tightly into the area underneath my testicles and it feel a like a tube of sorts is being squeezed, (sperm duct, or vein, not sure) and it hurts. And I've twisted that one testicle in a 360 rotation round to see if it helps, but to no avail... it just feels really tight... I need help
