Does the redness look at all like a bug bite or the start of a rash? I had shingles last year near my eye (above, actually) that started out slightly resembling a bug bite, with some swelling and soreness. In a few days it got worse, redder, and started to resemble a rash. If there’s a chance it could be shingles, go in right away, it could permanently damage your eye if left untreated.
