I can't seem to use crutches because when I bend my knee past a certain point it hurts it. Also hanging it hurts it.

When I go shopping, I use the carts at the store or the motorized ones (when I am esp. bad). My son immediately runs to get me one the moment he gets out of the car.

I have a cane that I like, it helps a lot, however, it hurts my hand sometimes because you are basically pushing hard on it to support one side.

I would suggest a walker. It is a constant support. Rolls forward. Supports both legs like a shopping cart.

Hope this helps. Also, I am in hydrotherapy to try and get back my muscle in my right leg. (RSD in right knee) I constantly offset to my left because of the pain. Anytime I try to walk straight at all it hurts, well even when I walk guarded it hurts.
