anesthesia
"Succinylcholine was used as a pre-tubation muscle relaxer on my D & C outpatient surgery.  Approximately 12 hours after surgery I began to have severe muscle aches and stiffness. I could barely move. All my muscles were affected. I couldn't cough as my abdominal muscles were very sore. Standing, sitting, walking was met with intense pain. Sleep was painful as I couldn't adjust myself. I was given pain meds that only helped slightly. Pain lasted 4 days."
