Have had low back pain that radiated down right leg for more than 4 years. Iam not over weight, do not smoke or drink,and participate in Yoga exercises daily to help strengthen my back and stomach muscles. My first facet injections lasted more than 3 years. Last January, I was using a power tool and the pain with leg involvment started again, but with greater intensity. I had a second set of facet injections with little relief. Saw a chiopractor, which really caused other problems- hand cramping. Third set of facet injections was not effective. I am scheduled for a Micodisectomy on June 11. Will give an update in 4-6 weeks.
