anesthesia
"I've received spinal injections because after a serious car accident I've been left with severe pain and will do anything to relieve it. Anytime I get an injection, they give me propofol before the injection and I'm knocked out within a few seconds and then awake a few minutes after the procedure. After about 15 minutes I'm ready to get up and leave and am able to walk and function normally with absolutely no hangover or side effects."
