It happened again last night - I had a huge full body twitch while I was sleeping and wrenched my back because of the spasm. I was hurting real bad last night and had to get hubby up to get me more pain pills. I couldn't move well after that and now my neck is in spasm too. I have been doing so good but these body twitches just cause me to wrench my back and I am afraid it is going to do damage! Maybe I should call my doctor.
