I had back surgery 5 years ago almost to the date (I think it was on Feb 22). It was like turning a light switch on. I could barely sit or move and my foot was starting to fall (i.e. losing the nerve that kept it flat when I walked). The doc said I had to get in within the next 2-3 weeks or I could permanently lose the nerve. The disc was blown so bad and basically made a V out of the nerve. They removed 70%-80% of the L4-L5 disc and 30% of the L3-L4 disc. Have had no problems since, just a muscle issue now and then. This one I think is purely muscle related. I have no pains anywhere else except right at the bottom and it is more surface and deep in where a nerve would be.
Just very painful to move right now and DS is having his first sleepover here tomorrow night. Four 9 year olds.
