For me keeping as mobile as I can has helped to a degree. Though like now when I am in a very bad pain flare up my balance is off. For some PT with a person may help but for me it did not so I had to work on ways to progress on my own and keep mobile. I did very small increases of walking etc. I'm really struggling right now so have similar concerns about being unable. I am thinking of doing some other meds or treatments? So I guess I would ask you what meds you are on? Do you have numb feet? This is a side note from PN but how are your bones? I just ask cause with the falls to make sure they are ok. I have osteoporsis as well so why I ask. Feel better.
