A relative gave me a couple of huge bottles of the stuff, so I took it for a year or so for neck, back, hip, wrist and knee pain. Didn't make a bit of difference. One or two aspirins or ibuprofen worked better.
Topical analgesics work for me as well - salicylates, menthol, etc. I use them to minimize the ibuprofen. Gotta be careful with the topicals, especially salicylates - in rare incidents some people may experience serious reactions.
I'm hoping regular exercise will help, but I'm avoiding any hammering or grinding.
