The doctor started to think because of this delayed onset, which is what we see with this syndrome, that perhaps thats what it was. They did blood testing. They were able to detect it in her blood. The tick bites a then it bites a human. Then that causes an allergy to meat and dairy. We have seen kids grow out of allergies. Any chance people could overcome it with time .
