First my son had these little bug bites that had pus coming out of them. Then his eye had swollen up pretty good. We gave him benedryl and he seems okay now. However now for the past three days I've had huge welts that appear only after I itch. They appear on my forearms,feet hands,back,and legs. Even on my buttocks. It dosen't even look like I have anything untill the urge to itch is to great and i give in. Lastnight my lip became swollen and now I'm thinking whats next? Can someone please help?I've researched scabies,bedbugs and spiders. I don't have a clue to what is going on.
