@erma I've had dizziness and imbalance since Jan. 2020. I'm thinking that it might be related to long Covid. I have vestibular migraine along with PPPD and am not sure how the two (PPPD and VM) intersect. If I walk more than 10 minutes I become more dizzy and nausea kicks in, precursors to a migraine. This has deeply impacted my quality of life. I'm 75 and can relate to your situation. I have found some ways to reduce migraine attacks but the dizziness persists. I also have tried various tx with no help for the dizziness. I am speaking to my neuro again tomorrow and will let you know if he has any other ideas to try. It is not a crystal problem in my ears.
