Thank you lynn p. and thunderbear

I'm pretty sure it is a regular non harmful spider bite, because even since I posted, the hardness has softened and the size of the lump is small. It is still quite red but no more "drainage-yellowy scab", maybe because I've stopped picking at the darn thing!

I think it was a BIG spider, hence, the BIG red spot!

I loved your scientic logic, I guess I remember that about spiders now that you told me - nice thought isn't it? It doesn't bother me at all. I guess I'm not squeeeeemish like that. Not too crazy about worms is all, though they are good for my garden. Just so they know where they live, and where my house is. and they best respect my boundries
