Have a torn disc in lower back

I trust your doctor is treating you for chronic pain from your torn disc and you are asking how to relieve the pain from the muscle spasm.  There are a number of different techniques recommended for relieving muscle spasms.  Try moist heat for no more than 20 minutes at a time.  (Leaving heat on too long can do more harm than good.)  Then gently massage the painful area, stretching the muscle using long, flowing strokes.  Another suggestion is to alternate moist heat and cold packs – again no more than 20 minutes for each.  The cold packs help with pain and inflammation while the moist heat loosens the muscle and improves circulation to it. 

Hope this helps.
