Probably not a werewolf or zombie, it's much too small.
And I didn't feel anything, just woke up with an itchy red patch just over a week ago.
It looked rough as if I had scratched it in my sleep, so I assumed it was a hive, (I get hives now and again), dabbed it with Dettol antiseptic and forgot about it. Until it itched again. I dabbed it again and forgot about it. Until....well...you get the picture.
By the next day it still hadn't disappeared, usually an itchy hive would be gone a day later.
And I never get the red patch around a hive, just the itchy little pimple.
Site of the bite I reckon.
The red patch around it was larger yesterday, you might be able to make out the pink wider edge and where it goes down towards the armpit a bit? All of that was almost as red as the bit around the bite, probably from scratching. In my sleep.
Anyway, it itches occasionally, I forget that it is there until I scratch, then I apply more Dettol antiseptic. And hope it will go away soon. Or at least stops itching.
It doesn't hurt and I'm not sick from it, so it isn't a bite from anything venomous.
I'm not concerned, (much), but if it doesn't disappear in the next week, I'll see my doctor.
Do earwigs bite? I get them inside, they come through the cracks under the skirting board.
I have spiders too, I found a dead one in my summer pyjamas drawer in between two pairs of shorts.
