My husband has large circular red blotches all over his skin, chest, arm, legs, back he has atleast 12 of them, we went on vacation a month ago and got bite terribly by green head flies, he seems to think its related, they don't itch and are rash like, just big blotches that aren't going away, any suggestions. I looked up shingles, doesn't look like nor does he have those symptoms, he has had for over a week.
Thank you
