Can anyone give me suggestions to help with Arthritis?

I am 51 years old, but have had arthritis in my spine since my early 30's. I have pain pills and don't abuse them, but I've been on them for fifteen years. It's degenerative which stinks, but lately it's getting bad. I have an 8 year old child, and do animal rescue and work a full time job. I can NOT afford to be in pain like this, and I have to be able to move, so fuzing things isn't happening. Does anyone have any suggestions that might help? I took a header off the porch carrying two 5 gallon buckets (in the rain...hit a slick spot on the deck and the rest is history), and I couldn't move fast enough to brace myself. I am not okay with this! Any real ideas are welcome. Thank you!
