I was poked, prodded and stuck with a needle, but it turns out I'm healthy.
At least I think I am.
My doctor did suggest I go have some test done to check my thyroid. Apparently it felt semi-funky to her when she was checking it. She told me not to be alarmed and she was pretty sure it was nothing to be worried about, but that I should go have some ultrasound done just in case. They sucked some blood out of me today, but next week I have to go back for some other test.
On the plus side, I did get my medicine refilled, including stuff to combat my headaches. That alone makes all the poking and my sore arm worth it.
