Gabapentin is absolutely the cornerstone medication for my CRPS. The efficacy of it has been verified when we tried to wean off of it two separate times.

As others have mentioned, "your results may vary". It doesn't work for all, but does work for many. Sometimes a little tricky to find the correct dosage as with many drugs.

I have found from a number of doctors that gabapentin is very often the first drug tried when a person is suspected of having CRPS.
