Welcome to the forum, sorry for the circumstances.

Gabapentin, like many other drugs, can be tough to titrate to the proper "effective" dosage, which of course varies from person to person. But it is critically important to get to that effective dosage and some doctors bail out too early.

Gabapentin is my mainstay drug for CRPS. I had to go up to 1800 mg (600 mg 3 times daily) before I found relief. What your doctor is doing is prudent.

I don't think the edema or creep of symptoms is being caused by the gabapentin.

There are other drugs though which can be effective for neuropathic pain such as Lyrica, Cymbalta, and others. You might have to experiment a bit to find the right drug AND the right dosage of that drug. Have you tried any other drugs besides the gabapentin?

I'd type more, but my carpal tunnel is acting up. Hope this helps!
