pain
"Been using this for 16 months for ongoing knee pain following surgery. Works well, with minimal side effects. At this point I only feel slightly different and able to function quite well. Only side effect I really get is dependence which can be bad. But it helps with the pain considerably and I can't seem to get off of it. I'm 76 years old. I'd rather live out my life being able to play with my grand kids and enjoying their company then sitting at home in pain. Hope this helps."
