As mentioned above, the balance problem could be a low B12 level. Our B12 absorption becomes less as we age. Several years ago I had to walk with a cane just to keep my balance. At home if standing, I would lean against the wall or the kitchen counter. My B12 level was 85. Added to that I was later diagnosed with low testosterone (186). The two together made life horrible. Monthly B12 injections and daily Androgel have me back a normal life. Low B12 can also affect the nerves in the ears which could affect hearing. Might be worth checking, it's just a routine blood exam.
