Lyme Disease and a bad spider bite took my grandfather's life before I was born. From what I understand, nowadays they treat the disease by basically nuking it with antibiotics. Its probably best to talk with a doctor and see if you can get some more advice from them, or perhaps seek out a dedicated support group online. They'll probably have more tips and tricks.
That, and do some research on how to prevent the tick bite in the first place. When I was young my mom always made sure to point out that we needed to be careful during the times when lyme disease was most prevalent. If you're in an area with a lot of brush and you see deer around, you'll want to be careful. Deer ticks are the primary carriers of the disease. We'd always make sure to keep an eye out for the telltale bullseye shaped rash - luckily we never saw it outside of pictures online.
