In 2008-09, I fell down on a footstep and the edge of the step hit my back. I had mild pain and recovered soon. After that I started having pain which felt like pinching of the nerve and the pain travelled between hips and right leg. I ignored the pain and for extreme pain/discomfort took painkillers l. I'm still suffering from the pain. Recently I read about sciatica and herniated disk. My question is, is there a probability that I'm suffering from pinched nerve/sciatica caused by the fall?
