I also have low back pain. For me, one of the few good side effects of being on prednisone was that it helped to alleviate my low back and knee pain. Like Wrangler and my orthopedic doctor said, it is because of the anti-inflammatory properties of the prednisone. I also try to do a lot of stomach crunches daily to build up my abdominal muscles which tightens and strengthens the area around the lower abdomen/back and helps a lot to minimizing my lower back pain. One of my friends doctors prescribed this for his back problems and it helps him a lot. Good luck to you.
