So this past Saturday I finally went to see the doctor about the dizzy spells I've been having. (I realized, after I got there, that my existing GP doctor is listed as "in network" on my new insurance's website but also has a smattering of disclaimers around it saying that's no guarantee of coverage. So I've got that to worry about now, too. Man, healthcare in this country...)
She agreed with my assessment that it's most likely a result of allergies and congestion around the ears. She told me to buy some maximum-strength Sudafed (an ordeal in and of itself; I hate the hassle of buying Sudafed -- but hey, totally worth it since it's done such a great job of solving Arizona's meth problem!), use my nasal rinse, and drink lots of water, to get my nasal passages rehydrated and clear out the gunk.
I'm a few days in, and it's hard to say whether I feel better or not. The nasal rinse is one of those things that always feels legitimately unpleasant but does clear up the passages -- aside from the part where you drip varying combinations of snot and saltwater out your nose for the next few hours. When I'm not dribbling like a leaky faucet, I am breathing better than I have been.
Still feel congested, though. Still dizzy, and had a wicked headache today besides.
