What does a bed bug bite look like a giant pimple?

Well....: Bed bug bites may cause no sx's/signs in some except for 2 small points where skin was punctured by bedbug. When there's a reaction, it may show from an hour to several days after bite. It can cause itchy, pink, swollen, lesions w clear center. In cases of hypersensitivity blisters may develop. A telltale sign is linear track of lesions from sequential feedings – but that doesn't always occur.
