In reply to John Burns: You can test for Lymes disease but the test suffers from quite a lot of false negatives and, as it checks for antibodies, can't be done too soon. The 'Bullseye' ring or redness around a tick bite is an indicator of Lymes but isn't always present. Keeping the tick so that, if you get symptoms that may be Lymes, the tick can be tested is advised.
I believe there is a big variation in the awareness of Lymes between doctors. A friend's brother is a deer farmer (so high risk of exposure). Last year he went down with Lymes but they had a massive fight to get him tested or treated for it despite ending up in intensive care. The consultant in charge of his treatment just kept telling them that 'We don't see Lymes disease here'.
I guess you won't diagnose any Lymes disease if you never test for it, even in the deer farmer with symptoms of Lymes where the family is telling you it is Lymes.
I'd definitely recommend the O'tom tick remover (get it from a vets) which you DO twist (clockwise when the moon is waxing, anticlockwise when it is waning. Or is it the other way around?!). If you use tweezers then don't twist as you are more likely to break the mouthparts off and leave them in you. The important thing is not to squeeze the body of the tick as it is more likely to regurgitate Lymes into you.
