What to do?

I've been in Texas less than 40 days and I've been sick twice. Not good! I just started feeling sick again yesterday. My tonsils hurt like crazy, my body aches and I have a fever of 160 (j/k, it feels like it). I really don't know what to take for it, I've just taken Tylenol for the fever. It's helped a bit, but the fever comes back after a few hours. Hmm should I let it subside or rush to the hospital and end up with a $1,000.00 bill!!!!
