My bones were weak (ostioprosis). I was falling a lot too and once I lost my balence and fell when I was just walking in my apartment. I knew that I broke a bone as soon as I hit the floor.
But I thought it was only one bone not 3 of them. One of the bones was in my ankle and two were in my shin bone (tibia).
I worried about my cats, but Felicia and Beau got along fine.
