Margo, if you can find a good osteopath it might do wonders. I have three bulging disks in my low back area, and was starting to get sciatica symptoms. Twice I've gone into spasm so bad I couldn't wiggle my toes, let alone walk, for a month! The curled position on a bike is hard on the body, so I was taught several stretches to use several times a day and it has helped so much, I rarely have trouble anymore.
