You find 30-50 crawlers per day? Dude. I guess it's a hazard of the job, eh?
At this level of exposure, you must have had Lyme disease already. I don't need to remind you that it can be extremely debilitating, comes in all sorts of weird forms with weird symptoms, and can take months and months to suppress. It can be carried by those fucking Lone Star ticks too, among other nasty ailments.
As an outdoor professional, I'm sure you know to wear long sleeved pants and shirts (dress shirts are great for this) and tuck your trouser cuffs into your socks. Applying >50% DEET products in rings around knee, chest, and elbow has also reduced the "crawler/embedded" ratio, at least for me.
In southern NY and on LI (especially Shelter Island
) the rate of infection is very high compared with the number of burrowers.
If you're interested in speciating a tick, you can send it to the NY State dept of health. I do this all the time because I still have trouble telling the difference between deer tick larvae and deer tick nymphs (more dangerous). If you would like to have the tick tested for bacteria associated with Lyme disease, you may engage the services of the state of CT through one of their analysis programs.
As far as blood tests go, for some reason Quest labs has delivered more "negative" Lyme disease tests (like Western Blot) than other labs for the same person. This isn't a difference in standards of interpretation either.
