jenna ,andy-hughes and tups ,thank you all for your replies...it is interesting to see how it affects different people ..this relative was bitten many years ago and had a lot of the symptoms and it has only just been diagnosed ,after yearsof ill - health and endless visits to the doctors!Not much was known about it then in the UK but I understand it is on the increase here!
It does appear it needs treating in the early stages with antibiotics as severe problems can set in if left !
