Don't worry about it too much Andy mate.
I must have been bitten by over 100 ticks over the years (some of which have been in for days). I can imagine Norrie will have been bitten by over 1000. Either neither of us have Lymes or neither of us have spent enough time without a hangover to notice the difference...
Joke. It is a serious issue. Wathc out for the signs of infection. The bullseye "bruise" in the area of the bite is the main one. Check yourself in a full length mirror when you come back from any crag where you walk through undergrowth. Grab them at the point of contact on you skin with tweezers and twist either clockwise of anti-clockwise.
