I, too, had a balance problem when I was paralyzed from the neck down (for two weeks) after taking the flu shot five years ago. The shot attacked my spinal cord and it was a slow recovery from a wheel chair to a walker to a cane and now I'm FREE! I recovered about 98% and that's the highest level I will reach and feel thankful that I'm there.
What helped me tremendously was a shower chair with arms. I really didn't need grab bars as I could put my weight on the arms of the chair while standing under the shower head. After about three months, I didn't need the chair for balance. I still have to be careful on ladders but know my limitations.
Safe travels,
MM.
