Understanding Insect and Spider Bites -- Symptoms
What Are the Symptoms of Insect and Spider Bites?
Most insect bites produce only minor irritation, with symptoms such as:
- Swelling at the site of the bite.
- Itching or burning.
- Local numbness or tingling.
Bites of poisonous spiders and scorpions may produce these symptoms:
- Intense pain at the site of the wound.
- Stiffness or joint pain.
- Muscle spasms.
- Abdominal pain, nausea, or vomiting.
- Fever or chills.
- Difficulty breathing or swallowing.
- A spreading, ulcerated wound or tissue death.
- Dizziness, impaired speech, or convulsions.
An insect or spider bite can rarely cause a potentially fatal allergic reaction known as anaphylactic shock. Its symptoms include:
- Rapid swelling of the lips, tongue, throat, or around the eyes.
- Difficulty breathing.
- Wheezing or hoarseness.
- Severe itching, cramping, or numbness.
- A reddish rash or hives.
- Stomach cramps.
- Loss of consciousness.
Call Your Doctor About an Insect or Spider Bite If:
- You think you have been bitten by a poisonous spider or scorpion.
- You experience any of the symptoms of anaphylactic shock described above. This is a severe, possibly life-threatening condition. Call 911 or your emergency number immediately.
