I don't eat meat and haven't since I was sick in April of 2010 (
link to my LJ on it). A few days ago I read an article on an allergy spread by ticks in South America and that the Lone Star tick, whose habitat just happens to include the District has been spreading it, too. (Couldn't find the original article;
this one is from NPR a couple of years ago.)
I'm going to have my doctor check me for it at my next physical. Reading about this was fascinating, every single symptom or experience tallied with mine, and not just in the "I fell into a clickhole on WebMD" kind of way. It's also a little bit of a relief. So many people have commented that I must be faking or it's psychosomatic that I was beginning to wonder myself.
