I had pretty severe lower back pain with numbness and pain in my right leg. The MRI was not very informative, some degeneration some bulging, lots of inflammation; this had been going on for years. I had PT. meds, all the therapy but it got so bad that when I took my granddaughter to Disney I had to rent a scooter because I couldn't walk any distance at all. My ortho sent me for injections in my spine followed by more PT in the pool - the injections made a huge difference. I think because in my case, much of the problem was inflammation. If your pain is the result of more mechanical issues, it may not be as effective, but I know that my doctors have always recommended the most conservative approach first before considering more drastic solutions like sugery. Talk to your doctor, maybe a consult with an orthopedic would be in order?

The advice I got from the physical therapy people helped a lot too. Your RA limitations make walking difficult so the amount of exercise you get is smaller and smaller. It's amazing how quickly the muscles lose strength and the ability to support your core - an important part of maintaining that silly upright position we humans feel we need! I know that PT in a warm pool was the best for me! They taught me exercises to strengthen my core and help support my back without putting extra stress on my achey joints. If your insurance covers it, you might ask either your rheumy or ortho for a PT prescription and afterwards look for a local heated pool with arthritis classes. These can help you stay active with the added benefit of the chance to make some new friends.

Talk to your doctor, and ask for some help. Hope you feel better!
