It is a nerve and a crushed disk. Last year there was a man at the place I worked he should have been a hoyer lift from the start but they felt since he could stand he could be a 2 person stand pivot. Well that went right out the window because he decided to use out arms as swings. The person I was helping didn't warn me and let go of him thus causing him to fall as well as me and I fell right onto the metal sink crushing a disk and damaging the nerve with the patient landing on top of me. So the incident caused even more damage than it had been in recent years.
