Here's why:
* Urine doesn't neutralize the venom: Sea urchin venom is complex and doesn't react to urine.
* Urine can irritate the wound: It can actually increase inflammation and pain.
* It's unsanitary: Urine carries bacteria and can introduce infection to the wound.
What should you do instead?
1. Remove visible spines: Carefully remove any spines still embedded in your skin using tweezers.
2. Soak the wound: Soak the wound in hot water (as hot as you can tolerate) for 30-90 minutes. This can help deactivate the venom.
3. Apply vinegar: Vinegar can also help neutralize the venom.
4. Seek medical attention: If you have severe pain, a large number of spines, or signs of infection, see a doctor.
Remember, it's better to be safe and stick to the proven methods for treating sea urchin stings.
