I was back stepping relatively slow, I planted my left
foot turned RIGHT, and attempted to accelerate, not only did it not happen, but I found my self on my knees in teeth grinding pain. I got to my feet and attempted to walk only to find that I could not bare any weight on the ball of my LEFT foot... Not only did it severely hurt, but it felt as if I had absolutely NO muscle to support it. I managed to walk / hop on the heel to a bench and about cry.
