I am a male in his 30's. About 10 years ago, I began getting frequent urination, which would often wake me up at night. (I also began getting more and more fatigue at this time.) I also would drip urine a bit longer after urinating than I used to, and so I would wipe the end of my penis with toilet paper. About three years ago, I was sitting at a desk with my legs propped up and I twisted around suddenly. A day or two after that, as I was wiping myself with toilet paper after urinating, a very deep and unnatural pain developed in my right-side inguinal area (the pain also extended, at that time, up higher), and the pain became so bad I had to go to the hospital. No doctor has been able to diagnose the cause of the pain, which now does not extend higher than the inguinal area (and has not for years). I've been tested over and over again by hernia experts and every time they say resolutely I don't have a hernia. The pain is on the same side I had an appendix removed when I was 7 (decades ago), but is well below where the appendix was removed, so I doubt that's the cause, but I mention it since I'm no M.D., of course. If I try to touch the end of the penis, where the urine comes out, the inguinal pain that sets in later is horrendous. Strangely, though, that pain never occurs anywhere in the penis itself. Finally, if I try to consume even a ridiculously tiny amount of lemon juice, lime juice, or ascorbic acid, I get the inguinal pain. I am hoping that this last factoid in particular offers a special clue as to the cause of the problem. Thank you.
