I used to like a few pints, 4 or five on a Friday night, I then after I could not pass urine my stomach was very bloated and sore, sometimes would not recover for a few days. I had my urine tested, nothing wrong? I stopped drinking for a couple of months, persuaded to start again, same routine every Friday night. It was ok for a couple of years, then it started again? Had kidney's tested urine etc, nothing, this has been going on for years? GP starting to lose patience? I have NF2 could it be something to do with that, neuroma, or am I being a bit of a hypochondriac or a sign of age? Not much is known about the effects of NF2 on internal organs?
