Mary Thompson, 76, is a retired school teacher. She recently had a hip fracture but had not fallen. She tells the story of simply walking across the street "I might have tripped a little bit, but I did not fall" Mary has muscle imtability and twitching. She is back in the hospital for removal of her parathyroid glands.
