Insect bites? Spider bites? (I realize the latter are not common) About 8-10 mm in diameter. Mildly itchy; painful to touch, very slightly raised.
I awoke to find 3 of these spots on the outside of my thigh. All are very close to the photo, other than one being 8mm and the other two closer to 10 mm.
As mentioned in the title, they are mildly itchy and painful if I press on them. The central portion is very slightly raised (maybe 1/2 mm) whereas the perimeter (where the more reddish circle lies) is regular skin height.
