How bad can pain get? (part II)

well I found out how bad pain can get. I was in the hospital after surgery and a physical therapist tried to move my leg around. She forced my leg the wrong way and did something because suddenly the pain got so bad that I started screaming and went into shock. I was sobbing uncontrollably for about 10 minutes. That's the kind of pain you normally can only get with badly trained medical personnel during a hospital stay. There is probably worse pain than that but I hope to never encounter it.
