osteoarthritis
"I'm a 58 year old woman with osteoarthritis and pain in my knees.  Tried a lot of things that didn't work including other NSAIDs, shots, tramadol, but have been on this for about 2 months and it is a life saver.  I am able to walk 2-3 miles a day with minimal pain, walk up and down steps, and sleep better.  I haven't noticed any significant side effects -- perhaps very mild constipation.  I will be deferring the knee replacements for a while thanks to this drug.  I take it twice a day, 75 mg."
