Had trouble with 3 discs (bulging/collapsing) pressing on my sciatic nerve, made my life an utter misery (being the generous type, i shared it with the wife), one microdiscectomy later and i was right as rain. Until scar tissue formed on the operation site and the pain came back. Been offered a second operation to fix it, but they've told me the odds of the "bad things" (paralysis, death, erectile disfunction, etc) were higher than before, i was **** scared the last time around so i'm sticking with the pain killers and being a grumpy git around the house.
Developed carpel & (according to the surgeon who examined me) cubital tunnel syndrome on both sides. Choice of putting up with weak grip and tingling or being opened up 4 times. And it didn't work out so well the last time they stuck the knife in me .... (it's like a toothache, ruddy nightmare for days on end, then the day you decide to get to the dentist the pain is gone and you can't work out what the bother was about, rinse and repeat)
Mix in depression and acid reflux for good measure.
