Uh…. Go to the doctor?!

(1) Go to a doctor. (2) It is probable that you will learn to use both feet if you try and/or the bad one will get better. A Personal Experience: Cancer of the esophagus was detected in me 3 years ago. I had a major surgery followed by chemotherapy once I healed from the surgery. I wound up with neuropathy in my feet and hands as a result of the chemotherapy - But I am alive and the cancer is in remission. The neuropathy affects both my sense of feel in my hands and feet and gives a tingly uncomfortable pain. As you have learned feedback from the nerves in your feet and legs is part of your balance system. I see my cancer specialist regularly and a neurologist. I have found some things that help the pain or discomfort from the neuropathy - mostly a CBD oil cream for pain, and Alpha-lipoic acid 600mg (a supplement my neurologist told me about). I have had a slight improvement, but I suspect the biggest improvement was learning accommodations to allow me to get around more safely. Part of that was from therapy from a visiting nurse in learning walking and using a cane the right way - It’s not obvious, don’t kid yourself. You will find ways to improve your ability to get around. It’s somewhat quicker if you get medical therapy to teach the best ways to get around safely. And there are things that can sometimes help your body’s situation. By the way for most people, your body uses internal feedback from your nerves in your body, your vision, and your inner ear to maintain balance. Once we are no longer infants, we mostly do that without noticing we are doing it. You can use a cane for balance - I do that. You can make sure that, for example when in the shower and you wash you hair or face so you cannot see, that you have one hand on something sturdy in the shower to help you keep your balance. And over time you will notice less and less the accommodations you use to get by. You can survive this.
