My diagnosis was by the ENT doctor. The inner ear does two things. It allows you to hear and it helps you maintain balance, because mine doesn’t function properly my balance is off. The idea of the exercises is to retrain the brain and stimulate the inner ear, to improve the balance.
I have a post note with a big X on it on my kitchen cabinet that is eye level. I stare at the X and move my head from side to side to the beat of a metronome, which is going 120 beats a minute.
I repeat that moving my head up and down. I do this three times for a total of six minutes. I do the whole exercise again Two more times during the day. This for a total of three times a day, and I try to space it out equally. I saw improvement after about 10 - 14 days.
Hopefully this will be helpful for you. Keep me posted.
