It seems I now have something in common with Otzi and Ray! Living in the environment up here I'm always very careful about ticks and very very rarely get any (average one a year max). About 3 weeks ago I found what looked like a fresh bruise and I had partially tripped cathing my leg on a branch the day before. There was no sign of any bite and no tick. About a week and half ago it had developed in to the above which is Erythema migrans, a clear sign that I'd been biitten by an Lyme infected tick. As soon as I saw it I made a GP's appointment and decided not to say what I thought it was and let the Doc tell me. She was well on the ball and diagnosed it within seconds, a sharp intake of breath followed by 'I suppose you know what that is?' A course of antibiotics was the way to go, 100mg twice day. I did go armed with information from the LDA (http://www.lymediseaseaction.org.uk/) and after a short disscusion about my prefered treatment she agreed to give me an increased dosage of 200mg twice day for 3 weeks. Had a blood test yesterday and have to wait for the results but it seems that a negative result does't mean you haven't got it! Thankfully due to the fact that I developed the rash, apparently only 2 thirds of cases do, hopefully it's been caught early enough and so far, I've not had any ill effects. IMHO the LDA website above is a great source of information and worthwhile spending some time on.
