lyme disease, neurologic
"I have gotten a tick bite but the ring wasn't distinct enough for the doctor to verify it as Lyme, he prescribed doxycycline for me. It works rather well actually, considering I had an "possibly incurable" skin infection in my hands, this drug was the only thing that worked against it. So in the end, it seems that I didn't have Lyme, but all my other infections were cured."
