Several comments here, my brother got Lyme in November a few years ago and it pretty much has destroyed his health. Most doctors are clueless about it. He was diagnosed so late that it was imbedded in his joints etc.
-If you finds a deer tick on you, you can send it to tickreport.com or ticknology.com for testing.
-That said if it Is a deer tick and has imbedded go in and INSIST on 21 days of Doxycycline. With all the super bug scares the doctors only want to give you 10 days. You must have 21 days to catch the 2nd life cycle of any organisms. I know people who have not been able to get 21 days so mail ordered it from Canada. My wife found a tick and talked them in to 21 days.
Lyme is no joke and can manifest itself in many nasty ways. We also have treated a couple pair of pants and some stretch gaitors at InsectSheild.com. Knee high rubber boots, gaitors, or tuck pants in to socks are very important steps. Once they get on your legs they travel up to pits, hairline, and other soft spots to imbed.
