Hi Nancy
Welcome to the Board, but I'm so sorry it's because you've been dianosed with RSD!

This Board is such an amazing resource of real information and support, it's the best place I've found to help deal with and learn about this terrible disease. I'm lucky I found it soon after my Husband Joey was diagnosed with RSD after a foot surgery last March.
The disease in his foot has morphed through many different stages through the past year, and to start, I would recommend you to get a notebook to keep a Diary of your symptoms and the myriad of medications you're likely to be trying in different dosages, so you can keep track of side effects...I wish I had kept a better record. I wish I'd made a video documentary too!
Anyway, Joey used to have horrible electrical zapping, he'd say it felt like termites eating from his bone marrow out. He was put on Neurontin for the zaps, which DID help, but ended up turning him into a horrible zombie as Dr. after Dr kept raising the dosage (It's normal to get referred to quite a few different Drs. in your search for relief). Finally I took charge and put my foot down and tapered him off the Neurontin completely. He went through many other medicines, most of which he doesn't take anymore, but for the cramps he still gets, Valium has done the job since the beginning.
One crazy thing about this disease is how there are a thousand different symptoms and everyone has their own custom mix...and everyone has their own reactions to medications and treatments....that's why this Board is so wonderful. Drs often have outdated info, and just haven't seen so many different cases to understand how varied your case could be from someone elses. I hope you have a support network, especially helpful is to have someone like me (a non-RSD'er who can be your "Health Advocate") who can clear-headedly accompany you to appointments and ask questions and tell the Dr things you may not think of when you might be ***** from Meds.
Good luck in your journey, I hope you find relief quickly, and I hope you continue to post with us here on the Board!
