What Are the Effects of a Black Widow Spider Bite?
When a black widow spider bites the skin, a person can experience a sharp, rapid sensation of pain, similar to that of a pinprick. Within 30 to 40 minutes, the skin surrounding the bite mark can appear unusually red, irritated, inflamed or swollen, warns KidsHealth, a children’s health information website established by the Nemours Foundation. The skin rash may appear as a red ring or circle and can be tender to the touch.
