Seems as though the 5 day trip in May I took to Killbear Provincial Park had some lasting effects....aside from the mental healthcare. I was bit by a Tick. It only manifested itself about 2 week...
I've had most of these insect infections, Lyme, West Nile, and years ago, Rocky Mountain tick disease. The last was hard to find, the tick burrowed up by my spine. The Lyme was caught early and a dose of antibiotics cleared it up with no issues.
Ticks are hard to keep off. Years ago, at Boy Scout camp in Northern MN, we all had to strip down and bathe with Fels Naptha laundry soap. I think it was a preventative to poison Ivy but us little Scouts never had a tick problem.
