Hi I have a abcess or boil or cyst on my testicle skin, and I feel to have similar thing in my urethra near the tip of penis, as it pains during erection and suffering form sexual dysfunction also I did MRI, nothing came in MRI or ct scan of pelvis area I am attaching the photo, could you tell me what do you think it is, an abscess or boil or cyst I had nearly 100s of them before on testicle skin and penis head with a lot of fluid coming out of them, after that it cured. But I feel there are some solid ones (fluid not coming out any more) internally, like stomach, throat, urethra, between testicle and groin) but inside so cannot see but I can feel it, and testicle skin which I would like to send you photo Could you tell me how can we diagnose internal ones And what is the cure?
