Oh, Sheena, I can so relate. My worst fall ended with a torn rotator cuff. I agree with Snoopy, it's time to build your arsenal of equipment to protect yourself.

My immediate reaction to the stairs is to add a second railing so that you have one on each side. Whenever possible, I throw whatever I'm transporting either up or down. When it can't be thrown, I do it in stages: move it up, put it down, move me up and stop, move it up some more, move me up some more...

I use a four-wheeled walker with a seat in the house, the seat is my hands for carrying things.

Slow down. That's the best advice my PT gave me. Just slow down, look around you, make decisions before you move, concentrate on the actual movement whenever you move your body from point A to point B.

Footwear is a huge matter. Wear shoes/slippers that stabilize your feet, I only wear shoes that have a "cupped" heelbed, they give me lateral stability. I cannot walk with bare feet anymore, my balance is terrible. Clogs, Birks, or lace-ups work best for me. New Balance has a cool "rollbar" in the heels of some of their shoes and it makes an amazing difference for me.

It is hard, but with a little care, you can protect yourself. I hope you'll heal and feel better soon.
