Is spider bite dangerous?
Spider bites are usually harmless.
Many bites attributed to spiders turn out to have been inflicted by other bugs. Skin infections also have been mistaken for spider bites.
Only a few types of spiders have fangs long enough to penetrate human skin and venom strong enough to hurt humans.
Spider bites can cause redness, pain, and swelling, or you may not notice them at all.
Symptoms
Typically, a spider bite looks like any other bug bite — a red, inflamed, sometimes itchy
or painful bump on your skin — and may even go unnoticed. Harmless spider bites
usually don't produce any other symptoms.
Signs and symptoms of a black widow spider bite may include:
- Pain and swelling. You may have pain and swelling around the bite, which can spread into your belly, back or chest.
- Cramping. You may have severe stomach cramps, which are sometimes mistaken for appendicitis or a ruptured appendix.
- Sweating. You may experience chills, nausea, or sweating.
Brown recluse spider bites
The pain associated with a brown recluse spider bite typically increases during the first eight hours after the bite. You may also have fever, chills, and body aches. The bite usually heals on its own in about a week. Sometimes the skin at the center of the bite turns dark blue or purple and then forms an open sore (ulcer) that gets bigger as the skin around it dies.
When to see a doctor
Seek prompt medical care in the following situations:
- You are unsure whether the bite was from a poisonous spider.
- The person who was bitten experiences severe pain, abdominal cramping or a growing ulcer at the bite site.
- The person who was bitten is having problems breathing.
