I'm recovering from a serious full body injury. I fractured four vertebras in my neck C4-7, fractured my pelvis in 6 places, dislocated both of my legs backwards, knocked myself unconscious, tore my medial ligament, fractured my ankle, tore my shoulder amongst other things. When I woke from my induced coma I was paralysed from the waist down. There is a chance I will never regain full function in my left leg, am in constant pain and I will never regain full mobility in my neck, ankle/foot or shoulder. You're lucky you only damaged your hand.
