Yep, wood tick.
I'd never seen a deer tick until last year - and yes, tiny. We didn't have them in SW Virginia, and now they're here in zillions.
Some of my friends who hunt say that when they bag a deer, there's hundreds on them.
Last year I was walking my property line, watching of snakes, didn't touch bushes and such if I could help it - worried about the wood ticks.
I had deer ticks all over me - dozens, almost didn't even notice them. Found three had already bitten in. Pulled them off and stang like crazy and itched for weeks - yes weeks.
One in particular 2 months later was still healing. All 3 left scars. Wood ticks didn't leave scars.
I did go to a doctors several months later out of concern. He said it didn't look like I had Lyme - no circle rash around the bites. But he did script me anti-biotics just in case.
I don't think I need to walk my property line this year. These little nasty things now get my respect.
