osteoarthritis
"I woke up one morning 6 months ago with severe lower back pain. Since I have stomach problems and am unable to take oral NSAIDs, narcotics or Ultram, I tried Lidoderm patches without success.  Then I read about Voltaren gel in Arthritis Today magazine and asked my doctor for it.  It has worked well and this is the only way I am able to sit without severe pain. "
