I am alive
I woulda had an update sooner, but the house is sold, I got the job, and we're packing up junk and hauling other junk away.
As for the bug-bites, I put some Benadryl on it. That knocked the itching right out. I also had one on the back of my neck that I didn't notice until later.... Now the one on my arm, and the one on my forehead (the ones that got treated) are gone - and the one on my neck is still there, although it's not itchy right now.
Didn't get sick, and there were no ill effects - so I guess it wasn't anything poisonous.
Now when I lifted that fence up and saw all the bugs and spiders, there were a couple brown recluses - not sure if I saw a black widow or not, but I thought I saw one (that's the reason I was worried about bitemarks). No ticks.
And I'm allergic to certain bees, although, I'm sure that you know a bee-sting when it happens, not 10 minutes later.
Still have no idea what it could have been - but unless there's a possibility of long-term damage, I don't care.. they're gone.
Thanks for all the pointers fokes.
