Good thought. ABV is typically transient, and one would think that with three consecutive hyperbaric treatment there would be periods of waxing and waning of symptoms rather than a steady improvement as is implied here, but worth asking the OP. Also could explain the sudden vertigo with eating two weeks later if the ears remained clogged but one suddenly equalized.You have been directed to some top drawer docs....have you considered:
Alternobaric vertigo is a benign condition that affects individuals traveling in environments with changing ambient pressures, such as scuba diving or aviation. It is the feeling of surroundings spinning around due to a difference in pressure between the two middle ears1
I know of two divers that unequal pressure in middle/inner ear generated dizzy and spins.....you mentioned congestion.
Good luck and please post the outcome of exam.
@Rai24 , can you be more specific about how your symptoms changed with hyperbaric treatment? Did they come and go, or did they improve in a more linear way? How have they acted since then?
Best regards,
