My spine is falling apart so have dealt with sciatic for about 12 years. At times it gets so bad I can barely walk. I take Tramadol daily but it still hurts. This may sound crazy but find a good therapy masseuse. A lot of chiropractors offices have them now. I have at least 1 sciatic massage a month. My gal works wonders on me.
My chiropractor has a masseuse with her as well.
