question: Dear Doctor, Why have I got extreme pain in the lower spine, to the left of the spine which shoots down my legs at different times and sometimes up my spine, and also sometimes I get that pain in my legs, I know it is nerve pain. I had a car accident at the beginning of February. I also get pain which is there all the time across the base of my back ( hip area ) going from one side to the other, it is always there. I have muscle spasm pain in my legs. All the pain seems to be getting worse.
