Dear stainlessbox In the heading of insect bites
there could be three categories (1) Flea bites whch affects mostly legs they are not usually painful to start but tends to get itchy. Some persons could be extreamly allergic to flea bites. It tends to get infected. The places to get flea bites are households with pets, parks and sea coasts withn sand fleas. (2)Spider bite
They are usually largest bite they can go bigger in sevaral days and their number vary from 1 to5. They tends to get infected.(3)Mosquito bite These are usually affect the exposed areas like hands ankles fore arms.They rarely give any problem except persons who are allergic to mosquito bites. Checking your description I feel it could be fleabitis with infection. I am sure Pediatrician
will examine your daughter thoroughly and give appropriate advise and treatment. I wish her speedy recovery. Kindest regards.
