I decided to be all responsible and go get a physical since I haven't had one since the last millenium.
Serious mistake. First: my issues with needles have apparently not abated with time or with my new yogic breathing skills. I thought I was doing well--looking the other way, thinking about other things, breathing--only to wake up slumped over (that's why the chairs they use have a padded safety bar thing in front, it seems) with the whole staff of Quest Diagnostics looking at me worriedly and putting wet paper towels on my neck. It was a surprise pass-out, much more reminiscient of the Reading a Book In Which a Character Has an Uncontrollable Nosebleed incident in the laundromat in 1999 than the Attempting to Give Blood episodes of 1995 and 2000. So that's disturbing, because at least you want to have some forewarning of when you're going to pass out, you know?
Second: CIGNA will not pay for me to have a tetanus vaccine. This is very close to hilarious. Apparently vaccines are only covered under "medical" insurance and not "pharmacy" insurance, so when doctors do not stock the vaccine themselves (because they don't have the storage and it's more expensive to buy smaller quantities, apparently), but instead send you to a pharmacy to get it, the insurance company will not cover it. I spent 30 minutes on the phone with CIGNA and spoke to 4 different people, and they all said the only thing I can do is go to a different doctor who stocks vaccines.
Dealing with the medical system is enough to make me want to throw myself off a building in despair, and I'm totally healthy.
