Since you were still a child (with a developing immune system) you got sick right after getting bitten, which is actually a VERY good thing. Most healthy adults can resist the bug for a while and got get sick, and often dont even notice the bite mark. By the time they get sick the bacteria has "disseminated". The acute phase in my case lasted about 12 weeks.
It's not that people avoid treatment, it's that without a report of a bite mark from the patient almost no docs even think of doing the Western Blot for Lyme Disease to check for it. I saw about 5 docs in '06, one was even an infection disease specialist, and none of them checked for Lyme. Almost two million new cases of LD occur each year in the lower 48 states and few doctors have stayed current on the LD research, dont know how to ID it, or how to properly treat it. The CDC estimates 90% of LD cases dont get reported as such by docs b/c they dont know what they're seeing. The docs give their patients incorrect diagnoses like Chronic Fatique Syndrone, when what they need is huge doses of antibiotics.
