question: Last Wednesday I fell down with my back against a wall. My lower back has been a little sore since then but 2 days ago I had extreme pain all of a suddene. It hurt so bad that I cried. The same thing happened tonight. I take ibuprofen and tramadol for pain. I also take Valium. The pain tonight was severe. It lasted about a half hour. I am using a hot pack on it right now. The pain has subsided.
