The good news is it's not a tumour!
The bad news is I have some sort of virus of the inner ear that causes dizziness, vertigo-like sensation, and -- in the case of the morning that drove me to go to the hospital ER to seek answers -- extreme nausea and vomitting. The cure, apparently, is rest. And unfortunately, operating heavy machinery like cars and, er, AIRPLANES are out of the picture for now.
A cursery search online for labrynthitus, which is what we suspect, shows that this inner ear infection can take 6 weeks or more to run its course!!!
At first, I was extremely discouraged -- I had hoped to complete my PPL flight test before leaving for PEI mid July. The thought of taking several months off flying and then starting again, AGAIN, does not hold much appeal!!! But then I decided to make lemonade: Will take this next week off to rest as much as possible, and then will start a regime of daily studying so that perhaps I can at least get my written out of the way before I leave for PEI. Maybe.
Ugh!
