My son was swimming over the weekend at an area lake. He has a large, raised bite area on the right of his tummy. The bite itself (in center) has also grown a bit. The area is warmer than the rest of him. I've searched all insect bites and have found nothing similar - even on Google image search. Please help

There's very little we can do to help. We could list all possible insect bites, but that would be a very long list, and very time consuming. You'd still have to research them.

If this is a concern your best bet is to see a doctor. There's really no way to give a diagnosis online.

Good luck.
