I'm going to go out on a limb here and assume that lab tests for other bacteria need to be cultured as well, such as staph, which he did request labs for. Again, I'm not saying penicillin wasn't appropriate because I'm not a doctor. However, he continued to test everything but the one thing I asked him to, which it turned out I had. As I also said in another comment, he told me to continue using the high doses of penicillin (500mg IIRC) throughout him being convinced I had something viral, then an STD, and then HIV without ever changing the dosage and despite my condition getting progressively worse. There's multiple things I blame him for, the most upsetting being the statement-of-fact that I had HIV when I didn't. I also don't believe he was fired for no reason.
