Yesterday I had my left leg fully extended holding the break on a lawn tractor...the right leg was supporting my weight. We were jumping a dead battery in tractor..needless to say the tractor was in gear and I tried pulling it in neutral when I leaned down to do so my left extended leg eased off the break and tractor took off... my right leg stayed in place and the tractor proceeded to pull me forward...I felt something in my left buttocks pull out and pop like.... I can walk but I can not sit easily on my left button cheek and can not bend down with my left leg down...I have to put it back to bend down...
