chronic pain
"I have Crohn's Disease, 30 degree scoliosis, 14 reconstructive surgeries on my pelvis. Among many other issues.  I was mainly put on it because a Crohn's patient does not absorb oral meds very well. 
The Mylan brand is the only one that works (change 48 hrs) but I sweat profusely!  The doctor will not switch me.  It does work for pain, yes, but getting them to stick while constantly sweating is another story."
