I hope you find an experienced pain management specialist soon. There are many other medications you can work your way through to try and obtain relief from the pain and other symptoms. It is just a case of systematically working through until you hopefully find one or more likely a combination of things that help. It's tedious but there's no substitute for trial and error because its impossible for any doctor to predict which drugs at which doses will work for any given patient.

It may also be that the rash you had was coincidental and nothing to do with the gabapentin. A more experienced pain management specialist should have a deeper experience with the reactions of pain patients to that drug hence a more useful opinion on whether it is worth another try or not.

Meantime, the critical thing is to keep your hand and wrist moving even though it hurts or is difficult. The worst thing you can possibly do is stop moving it or try to keep it guarded from bumps and breezes. It's the toughest thing you will ever have to do and it seems counter-intuitive but it will be the best and cheapest investment in a recovery that you can ever make! You can't damage it or make the sprain come back by using it.
