question: hi - I fell down stairs on Saturday and landed on my lower back. It has hurt since, with mixture of numbness. I went to the emergency room on Sunday and after xrays it was diagnosed as a sprain. The numbness is starting to subside, and now I have very sharp pains that radiate ONLY when I touch the area. Other times, just a dull pain. I have been taking Motrin (perscription level) and icing it. BUT, I do sit at a desk most the work day. Is there anything potentially serious with the sharp pain?
