I saw Dr. B. today, and he's pleased with my progress. Wants another month of IV treatment though, which will bring me up to six months of antibiotics. He also switched me off of Flagyl, a particularly potent and bitter pill that I had to take every six hours. (I have to set the alarm clock to wake me at six a.m., though there's something like a guilty pleasure involved in shutting off an alarm clock and rolling over to go back to sleep.) One of the side effects of Flagyl (or its generic, which has one of those methawackadoodle names) is a tingly-numb-burning sensation in the fingers and toes. It's mostly a nuisance, although Dr. B. says it could turn into permanent nerve damage, which is why I'm now taking clindamycin instead.
The next checkup is March 4, and I have to have a CT and an MRI before that. But there's light at the end of my tunnel vision.
