I forgot to ask out of hours GP today - I have only been on gabapentin for 3 days to help with nerve pain - ended up having a rather unpleasent reaction in my arm muscles in my right arm (no swelling and nowhere else) and have been taken off it, so I've not taken that many but the pain is still pretty sharp, I can't grip properly or do anything with this hand (it's my dominent hand) - and I have work on Monday - not talking to my GP until mid-next week, when she is asking me how I am getting on ( will be an interesting conversation!) I am hoping I will be fit for work tomorrow - but if not your input will be gratefully received or anyone else here has been through this. I have been told this is a fairly rare side effect..
