I hurt my back a few weeks ago doing squats. Well I started having pain in my legs. went to the local primecare. They really found nothing.. Finally I went to the emergency room this past weekend and they did x rays, the doctor really did not find anything out. He said I could have pulled a muscle or tendon which is causing sciatica. he put me on Methylpredisone for 6 days. I am feeling somewhat better, I wonder how long this can last for. I have not really lifted anything since then, I did try one day, but my legs were not feeling great. any suggestions what I should do and how long should I wait to go back to lifting again. any help thanks
