So, long story short, they still don't know what in the blazes is wrong with me. The less negative news is that they're not giving up here. They took more blood on Monday, and while I don't really understand what's going on they're doing DNA tests and looking for more metabolic problems that could be causing all the headaches, fatigue, nausea, and occasional muscular problems I have. What is there even left to say at this stage?
