The answer to 'why is my spider bites' is that spider bites can have a variety of causes, including accidental encounters with spiders, spider infestations in the home, or reactions to spider venom. Common symptoms of spider bites include redness, swelling, pain, and sometimes more severe reactions like nausea or muscle cramps.
In most cases, spider bites can be treated at home with over-the-counter medications and basic first aid. However, if the bite is from a venomous spider like a black widow or brown recluse, it's important to seek medical attention right away, as these bites can be dangerous and require professional treatment.
