Hi steif
I can only tell you my experience with amitriptyline. I was prescribed it about 6 years ago to help with sleep which was lacking due to joint & muscle pain (misdiagnosed with fibromyalgia) - It helped me sleep okay but the side effects were a loss of orientation and space perception. Three days after starting I found myself reversing the car out of the garage but I'd missed seeing that I hadn't put the rear hatch door down - fortunately the garage door was all the way up and I didn't smash anything. Two days after that I realized I was driving on the wrong side of the road - again fortunately it was in rural area and traffic was sparse - no incident. It shocked me enough that I stopped my trip, turned around, went home and that was the last Ami I took. It is now listed on my medical files as causing an allergic reaction. I know many people can take it and have benefits from it but there are side effects to watch out for. I hope if you do take it that it helps with your neuropathic pain. I too am now dealing with neuropathy but that pain is reduced by a corticosteroid I take for another auto-immune condition. Have you found out yet the cause of the neuropathy?
Edit
Sorry missed that you'd posted in the RSD & CRPS forum so that question is answered.
