Ear symptoms came and went for me - sudden brief hearing loss, ringing in the ears, pressure, soreness (like a sore throat in the ears), and lots of issues with dizziness and disequilibrium.
On Christmas morning 2018, I woke up at 4 a.m. worried some sort of sonic attack was happening (people at the American embassy in Cuba had been worried about
a sonic attack recently) because I had diminished hearing, ringing, and absurd head pressure. I woke up my family because I thought maybe there had been an explosion or something, but they were fine! It subsided over the course of a few days.
Around that time I also experienced serious reactions to barometric pressure changes. A drop in pressure (like before a storm, especially a snowstorm) would just destroy me for a day or two. That's also related to the inner ears, partly.
The boat rocking feeling is called Mal de Debarquement syndrome (MDDS) by the way.
A doctor at Mt. Sinai Hospital in NYC treats it, but for you it should go away on its own as your infections and residual damage recede.
I'm definitely better in these ways. Not 100%, but when these symptoms do occur, I barely notice and don't mind. But at first they were maddening and scary!
