Mgt: A virtual consultation may be helpful to you and your pediatrician. A photo may be uploaded at that time. From your description, the insect bites may have caused an allergic reaction. Other possibilities include Lyme disease, is there central clearing of the reddened area? I would advise seeing your PCP, but a topic 1% Hydrocortisone cream may help to decrease inflammation.
