Yup, sad isn't it?
I used to be very active, chasing my kids around, played a lot of competitive tennis too, climbing etc. now I use crutches out of the house, hold on to furniture in it, and use a wheelchair for anything further than about 2 mins limp. It's frustrating, but better than not doing stuff
You use what you have to I suppose, but every now and then it does get you down being reliant on things to get you about. Hey ho.
Take care and remember you're not alone. We do get it. My CRPS is in my knee and both feet now. Socks and shoes are a major hazard all of a sudden!
