anesthesia
"I'm two days after gallbladder removal and was given this during anesthesia. Pain prior to surgery was excruciating but the all over pain from this is debilitating. Every leg, arm, stomach muscle is hurting to the point it's difficult to move anything. Even my jaws hurt. I will never use this drug again; I will deem myself allergic. I've recently had both hips replaced and was given a different muscle relaxant during those surgeries that did not cause any post operative pain. I'd never thought to ask about anesthesia drugs prior to surgeries. Due to the horrible pain I've experienced with succinylcholine, I will be certain to ensure its never used on me again.  Other sufferers say it lasts about 4 days. I hope that's the outcome."
