Hello D, and welcome!!

I've had RSD since '83. And, I was a "test dummie" for lots of things and doctors.
For the past 20 years, I've settled on Methadone, (No real side effects, except constipation, it can slow your breathing if you're not healthy in that area, or take too much) and, it's very inexpensive. There is no "Buzz".
I also take Valium, and a muscle relaxer at bedtime.

(I have other injuries, that I take other things for, but won't get into that.)

I hope you can find a good neurologist, call a University Hospital, and find out if their neurology dept. is familiar with RSD. They should be.

I know quite a few folks who take, or have taken neurontin. They have all put on weight. Lots of weight, with the higher doses is the complaint I hear the most.

Hope that helps, and hope you get some relief.. Keep moving. RSD is a monster.
