I am having severe lower back pain. I can t move without a sharp pain that runs from my lower back into my left leg. I went to the ER yesterday and they prescribed me 3 different types of medicine. I have used them and so far they are not helping at all. Today I have started experiencing an even worse pain that goes from my back through my left leg and then I stand my left leg starts twitching uncontrollably what should I do? Can this also be caused by a car accident that happened on March 9, 2015?
