Hi dcneedshelp! I can certainly relate to your story. I have crps in my right leg that affects my hip, knee, ankle, and foot. Crps came first then i broke my ankle and it caused such a flare. I couldnt wear the boot due to the searing crps pain in that ankle n foot. When the cast came off the doctor wanted me back into the boot but i said no way, so he showed me how to wrap it with an ace bandage. Then i bought an ankle brace /support online. Its black, you slip your foot into it and there are shoe laces that you tighten and tie. Looks like something a wrestler would wear. it kept my ankle stable so i could walk a bit. It's thin enough to fit inside a sneaker. I wore it until i gradually built up the muscles of my ankle. Itkeep up with those PT exercises at home if you can. Side to side movement was hard for me too
