My symptoms started with an acute 5 weeks from the moment I pointed the shower into my ear. Then they disappeared mostly except for a fluid sensation and then returned 5 months later and escalated for 6 months.
I suspect the escalation was the issue getting worse due to healing process. As an imbalanced fluid gets trapped the pressure goes up and this pressure causes all sorts of symptoms.
Sounds like Secondary Hydrops to me. But that’s just my personal opinion. If you were in the UK I’d recommend my doctor who is very pragmatic.
Diet and treatment is identical to MAV though but knowing the source of the issue helps with dealing with it psychologically: getting a very serious migraine complaint out of thin air is just silly imho.
IMHO you are too young for anything age related so trauma has got to be an area of interest, as would something congenital …but if you’ve never had ear symptoms prior to that trauma, well …
Btw my old boss was hit on the head and knocked out during a basketball game. He took a flight 3 weeks later and became deaf in one ear … we have got off much more lightly and I believe there is a strong chance of full recovery.
