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. Symptoms can 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
