What is a common symptom of a spider bite?

A common symptom of a spider bite includes systemic reactions such as fever, chills, and nausea. Many spider bites, particularly those from venomous species like the black widow or brown recluse, can lead to more extensive systemic symptoms beyond the localized pain or inflammation at the bite site. The presence of fever and chills indicates that the body is responding to the venom and potentially fighting off infection or dealing with inflammation as part of the immune response. Nausea is also a symptom that can occur due to the release of toxins from the bite, which can affect the gastrointestinal system.

In contrast, symptoms like severe abdominal pain can occur in some cases but are more typically associated with other medical conditions or types of envenomation. Loss of appetite and neurological symptoms such as headache and dizziness can also occur, but they are not as closely linked with spider bites as the systemic symptoms of fever, chills, and nausea. Therefore, the correct answer highlights the broader systemic reaction that can result from a spider bite, which is more relevant in the context of understanding spider bite manifestations.
