I was able to get all this information about Lyme Disease from a site. The link it sat the bottom of the page. It was decided that my mother had Lymes Disease even before I was born, so with that, every child in our family has it. Most Lyme Disease is not diagnosed because of the fact it has so many symptoms. It is never the same between two people. There are five in my family and none of us are the same, but we all share this disease. Below are most symptoms and misdiagnoses.

Early symptoms soon after exposure by tick bite:
