I know a few people who are suffering from the effects of those little blighters! One of the guys caught it in 1997 and he is still suffering from it now. The doctors thought he was mad suggesting it was Lymes disease as it wasn't common in our area. (NRW, Germany) Wrong! Don't underestimate these tiny little guys. If you do start to feel any of the symptoms you must go and get it checked. I always get covered in em when I take my dogs for walks in the woods but always check myself when I get in. A good strip search should sort you out.
