I do have similar symptoms foggy feeling, cinder block head, dizziness (non-vertigo), imbalance (worse with fatigue) etc., Not much help from any one after all the tests, MRIs many times.

Interesting to know about BVD and thanks for the message. For me sound (even fridge noise), people talking, street noise, stores etc., makes me dizzy. Ear plugs helps some what.

I will be seeing a so called specialist in 2 weeks and had to discuss seriously about this.
