<s>[INST] Hi, im 15 and suffered a mild testical injury jumping to a pool, it was painful for abit but subside in a few minutes, the next day at night, i masterbated and i began to feel an odd ache in my right testical, the next morning it was pretty painful and ended up going to the ER, said it wasnt anything major, then I went to 3 more doctors and all of them said it was just an inflammation of the testicals, over the next few weeks it slowly went away, now 3 months past and it's come back, but on my left testicle, i have minor pain but its annoying, and i experience pain when i hold in urine for a period of time and the testicle is tender and painful when i touch it, i dont know whats wrong [/INST] Thanks for asking in healthcaremagic forum   Inflammation and pain due to injury might have caused you problem at first.   But now inflammation and pain without injury may be due to infection (epidymo orchitis). So, please visit surgeon for examination and further management.   All the best. </s>
