Anybody have any good ideas for natural remedies to help with arthritis?

I had back surgery a couple of years ago and now I have arthritis in my back. I can’t afford to spend the money for the prescription my doctor wants me to take (even with insurance it’s 5 a month). I’ve tried drinking cherry juice, which seems to help, and was wondering if there are any other natural remedies that might help.

I have horses, so I stay as active as I can with them, but some days I get out of bed and I’m so stiff and sore that I can’t even stand up straight.
