I had hypothalamic lacunar stroke on 01/09/09 with subsequent thalamic pain syndrome on my right side arm/hand & leg/foot/toes. Constant tingling/burning/tightness/numbness & cold my entire right side of body. After stroke, my doctor immediately put me on 75 mg Plavix same day. After putting up with syndrome for 4 weeks, I went to my neurologist Thursday, 02/05/09 & told him the pain was really getting to me. He prescribed Lyrica 75 mg twice a day. He told me it would relive the tingling/burning, but not the tightness/numbness. He was right on! I've been on it for 3 days now and the tingling/burning sensations are just about unnoticeable now.
Hope this helps someone.
Check with your doctor to see if Tegretol, Neurontin, Lyrica, or Keppra would help. They're usually used for seizures, but also sometimes for thalamic pain syndrome. Good luck.
