Muscle Spasm
"Have used this for sciatic pain and muscle tightening, for 50 years now, about once every five years or so.  Love it.  Let&#039;s me sleep.  Methocarbamol, heating pad and rest for about 3 days -- and back to normal life again.  No side effects.  I am highly allergic to all paid medicines except for Aleve.  This is a life saver for me."
