I can so empathize with your condition! My hips were bruised for months - it was like my body didn't fit right into this space anymore and my clearance level has changed. Stairs were the worst! I lived in a three story house and if I lost focus for a moment and stopped counting the steps I'd fall down them.

**** This same thing has been happening to me lately! I woke up the other morning with a series of small bruises on my left arm (very odd, there were 4 of them, in a semi-circle, on the underside of the arm, not the top...) I know I had not banged my arm, or done anything to that arm, the day before, so I found it perplexing how I suddenly woke up with bruises!
I also get the same thing sometimes with stairs...I will find myself suddenly stopping or almost "tripping" (even if I'm calmly walking up or down, not rushing...) It's almost like you feel something there, or are trying to avoid something...hard to explain..... ********
