Okay, please don't laugh at my medical ignorance. I genuinely do not know. With Tammy's remarkable weight lost and her subsequent skin removal surgery, it's hard for me to imagine that small frame was trapped under all that body mass.
Look how "wide" Tammy is in these photographs in comparison to her post weight loss and skin removal. Do your bones also grow as you get to that size? Do the ligaments loosen to accommodate the extra size? I'm trying to imagine Tammy's pelvis being that small size but having those huge legs attached.
Tammy currently has this bow-legged walk. I wonder is that due to the weight or if she's always been that way as a child.
