I get ticks every year, and so far seems to be fine *achooo*
The best removal method is the tweezers as previously mentioned. They always head for warm parts!!!! so always check thoroughly but they can appear a few days later, from where i have no idea. If you do feel flu like symptoms you must, i stress must inform the GP of what you think you have as many are completely unaware of the disease and will tell you to rest and take vitamin C. I know of 2 people this has happened to, you are also looking for a large welt to develop around the bite 4-5 cm in diameter.
Most cases i have heard about stem from the New Forest and Exmoor i believe, but the disease is thought to be spreading. However it is still quite rare!
