ive been diagnosed with rsd since december.. in my left leg. and now i'm getting the same feelings in my arm. had an emg done because they thought it was carpal tunnel. tests came back normal so i'm guessing rsd might have traveled to my arm now? ive been on a total of 6 medications including neurontin, keppra, and now lyrica and none of them have worked. in fact, the pain is just getting worse every day. ive been on the full dose of lyrica (i believe it's 600mg) that my doctor will prescribe. i've been reading these posts and see that some of you are on lyrica (or other medications) and either opiates or anti-depressants at the same time. what exactly does mixing these do? i'm wondering if my doctor will ever suggest doing that for me? im kinda confused about all of this. he tried a nerve block but it didnt work.. he suggested a few months that i had some kind of epideral catheter put in me but he never brought it up again. i also see some posts about spinal cord stimulation and other things that doctors try. how come mine wont try any of these other options?? im new to all of this and it's scary and confusing and i am willing to try anything..
