Hello, Susie. We are all wondering if you went to the doctor. Was/is it a tick bite? Are you going to be okay?
Please let us know how you fare...
Red circles around insect bites are characteristic of a tick infected with Lyme disease. This appears as a "bulls-eye" and requires immediate treatment by antibiotics. What you require is an in-person evaluation by a physician.
By the description of the spots, it sounds like acne.
The big ones the size of a nickel sound like they have got infected or have got abscessed.
I would suggest you see your doctor to get them checked out and to give you a correct diagnosis on examination.
Best wishes.
I would also like to add that I dont have bed bugs, animals, flea's, or cockroaches.
