neuropathic pain
"I've been taking this drug for almost 9 months and I get no relief.   I suffer with leg pain that intensifies when I walk.   I've seen at least 5 different specialists; had scores of tests/MRI's etc 
and no diagnosis.  My final visit was with  Neurologists (I've seen two; one in Philadelphia and the other doctor in New York).  Unfortunately, I have not responded to this medicine and am now weaning off of it.  good luck to those who try it......SAD to say I  had no luck and my condition worsens every month."
