I have Lyme disease. the deer ticks came from white footed mice who are carriers. NOT ALL THE TIME WILL YOU GET THE BULLSEYE RASH. I did not have one. I started having trouble walking, I was limping everywhere and one morning i woke up and had an intense sharp pain in my knee that locked up so bad I needed to get a cane to help get around. Getting tested is the only way to know. it wasn't that expensive, this way if you know you can get antibiotics to take care of it. It will always be dormant in your system, but not nearly as bad.
There's a great movie with Alec Baldwin called Lymelife. check it out. Stay safe out there everybody.
