Medical Treatment

Immerse the area in warm water for 30 to 90 minutes. Use tweezers to remove any spines from the sea urchin. Remove suckers by applying shaving cream and scraping with a safety razor. Wash with disinfectant soap, and rinse well with warm water. Call your doctor for antibiotics and pain medication. Go to the emergency room immediately if you experience any serious complications.

When walking on the beach or in the ocean, be careful in rocky areas or ones that have coral. Do not handle sea urchins and coral, and avoid walking on areas that have them. Some spines may require surgical removal depending on where they enter.
