How can I Identify my nightly bites. I believe it looks like from a recluse brown spider, but every one says they are not here near Milwaukee. The bite has a white round circle a smaller red circle and a tiny thing like a bubble. It starts burning after a while. An ice pack helps.
Hi, Thank you for your query. I can understand your concerns. It seems to me that insect bite has caused a tiny blister surrounded by a red circle and further surrounded by a white circle. Red circle is due to erythematous reaction and due to capillary dilatation. White circle is a some kind of wheal due to exudation of fluid from capillaries and venues and thus compressing the soft tissue & decreasing the vascularity of the area. This kind of bulls eye patterns appear from the bites of Arachnids(spiders & ticks). The skin reaction to insect bites usually lasts for up to a few days. Regards
