Hi ya Joan!! My sister takes Lyrica75 mg. 3 times a day and she has never had a problem with it. I still have 29 of them left, as I took one (and only 1)and slept for a day and a half!! so not like me! So, I will give her the rest on Sunday. I went up to the Er this evening as my shoulder was on fire and the pain was like an ice pick being driven through it!! and the Dr. there said RSD only spreads from where you had your carpal tunnal surgery to the middle of your arm!! I'm like er.. ya.. ok!! she was in such a hurry. most of the Dr.'s don't even know what their talking about. she gave me a toradol shot.. took x-rays.the shot didn't even phase my pain!! so, I'm taking the neurton and will get my 2nd. block this coming Tues. thanks so much for writing me back!!
