Thank you so much for your reply. Yes, I am fortunate that I have my husband to help me. My daughter and son both live about 2 hrs away and they will come help as well. Your experience that you shared gives me hope, so thank you. It is scary because I don't yet know what is causing it. I have my first appointment with a neurologist 6 days before my scheduled surgery. My primary care doctir ordered Vit B12, thiamine, folate, fasting blood sugar, A1C and thyroid tests which wete all normal. She said the neurologist will order more blood work and try to find out what is causing it and that sometimes no cause can be found. I did notify the surgeon's office of the new diagnosis. Hopefully he doesn't cancel the surgery as I really need it. He plans to do the right knee first and then the left in 4- 6 months. I am 64 yrs old and and now have limited mobility due to severe knee osteoarthritis and this new diagnosis with numbness in bith feet and burning in calves with some tingling in hands and forearms complicates everything. Thanks again for your supportive response!
