Usually, spider bites are harmless, but if you experience certain symptoms, you should seek emergency medical attention.
There are only a few species of spiders in nature whose venom can be fatal to humans.
A spider bite can cause redness, swelling, pain, and discomfort.
A patient should seek emergency medical attention if they experience any of the following symptoms:
- You are unsure whether the spider was venomous or not;
- A sore has formed at the site of the bite and is growing in size;
- You experience severe pain after the bite;
- Abdominal cramps, convulsions;
- Difficulty breathing.
It is quite possible to mistake a spider bite for other skin ulcers, burns, or even infections. However, a doctor can easily diagnose a spider bite based on your symptoms and a visual examination. Most spider bites usually heal on their own within a week.
First aid includes:
- Wash the wound with soap and water. Apply an antibiotic ointment three times a day to prevent infection;
- Apply ice wrapped in a cloth to the bite for 15 minutes every hour;
- Elevate the bite area if possible;
- Observe the wound carefully - any visual changes are noteworthy.
In case of severe pain and muscle spasms, your doctor will prescribe appropriate medication. You may also need a tetanus shot. An anti-venom serum is given for bites from black widow spiders (a type of spider).
