My boyfriend is 18 & has recently been in a lot of pain. From what he has told me, his right testicle moved up & he had push it back down? After doing this, his right testicle is now sore and he is worried that this could occur. Also after ejaculation, he states that there is a pain and it does not feel normal. He has abdoniminal pain but has had that for three years so im not sure if tha is related? He has been to the doctor about his testicle and was told it could be chlamydia, but i have checked and this is not a symptom of that disease. He finds it difficult to stand up/walk for a long period of time. Has anybody got any further ideas?
