I have an L5 S1 disc herniation. Not sure when it started but felt the electric shock down my left leg at the end of March 2011. By August 15th it was pretty bad, the radiating down the leg. It took about 6weeks before an MRI confirmed it but I went to traditional doctors who went the conservative route of which no relief (other than a bottle of ibuprofen) was to be had. In the beginning of Oct I had a cortisone shot (ouch) because I just started to spiral downward emotionally. I am slowly climbing back up and found your site recently. I just bought 8 Steps so I don't have it yet and did sign up for Esther's class in April 2012 (sure hope I am fixed by then). Anyway, I still feel muscle aches in my butt and sometime down my leg but no electric shock so to speak. How do I know if this is a sore muscle from limited use versus the result of the nerve? ANy suggestions on how I should start this re-building?
