I have had random bites on my body that look and feel like mosquito bites but im almost never outside and i even checked for bed bugs but found nothin?

Bed Bugs are hard: to see because they are nocturnal. Bed bug bites may have no sx's/signs except for 2 small skin puncture points. A reaction may show from an hr to several days later. It can cause itchy, pink, swollen, lesions w clear center. If hypersensitive blisters may occur. Telltale sign is linear track of lesions from sequential feedings – doesn't always occur. Bites are in areas exposed while sleeping-arms
