Spider bites are a common concern, especially in warmer climates and outdoor environments. While most spider bites are harmless and resolve on their own, a small number can cause more serious reactions that require medical attention. Understanding the different types of spider bites, their symptoms, and appropriate treatments can help patients respond quickly and safely.
