muscle spasm
"Went to the Emergency Room with lower left back pain and numbness in left leg.   The doctor prescribed Vicodin and Valium when didn't eliminate the pain, but helped manage until I saw my GP.   She conducted no exam and decided to discontinue the Vicodin and Valium and put me on Methocarbamol and recommended physical therapy.   Needless to say it was back to the emergency room that night and I'm now looking for a new GP.   Only made things worse - she was an idiot."
