[Ellie May]

I'm not sure about blue but Ellie had red spots on her belly about a centimeter away from her incision. It ended up being normal.

I don't know if Benadryl will help an itchy incision because it probably isn't an allergy but if the vet told you to, I guess it wouldn't hurt to try. Ellie's dose is 1/2 teaspoon and she is just over 5 pounds. Does she have a onesie or e-collar?

If the stitches are dissolvable, she may not need follow-up although they should look to make sure it is healing either way.

When in doubt, have them look at it. It is better than a problem going untreated. I had Ellie's vets look at hers twice before her staples came out and it was no charge.
