Coral Scrapes and Urchin Punctures: How to Handle Maui’s Most Common Ocean Injuries

Maui’s beautiful beaches invite residents and tourists alike to snorkel, explore tide pools, and enjoy the warm Pacific water. But even though the water may look calm at the surface, it can hide dangers — and an unexpected encounter with a jagged coral reef or a prickly sea urchin can change your plans in a moment. 

Knowing what to do in the moments after a skin wounding-injury can go a long way toward protecting your skin, preventing complications, and helping you feel better, too. Here's what to do, what to watch for, and when to visit our team at Minit Medical Urgent Care and Physical Therapy.

How to care for a coral scrape

Coral is beautiful to look at, but it can also be deceptively sharp and rough, which means even a minor encounter can leave you with an open wound. Some coral injuries leave you with tiny bits of coral or other debris embedded in your skin, which can delay healing and increase your risk of infection.

Clean and protect the wound

If you’re cut or scraped by a piece of coral, leave the water and rinse the area gently and thoroughly with clean water and mild soap. If there’s bleeding, apply gentle pressure with a clean cloth or surgical gauze until the bleeding stops, or at least slows. 

Once the area is clean, cover it with a sterile, non-stick dressing. To keep the wound clean as it heals, change the dressing every day as well as whenever it gets wet or dirty.

Signs to watch for

Like any skin wound, coral injuries can lead to infections that can pose serious problems for your overall wellness. If you notice increasing redness, warmth, pus drainage, or swelling around the wound, or if  you have worsening pain or develop a fever, it’s definitely time to visit our urgent care clinic for medical evaluation and treatment.

Deep cuts, injuries that won’t stop bleeding, and any wound that has debris embedded in it should also be evaluated by our team right away.

What to do after a sea urchin puncture

Known locally as wana, prickly sea urchins hide among rocks and reef formations common along Hawaii’s coastline. Their sharp, brittle spines can easily pierce your skin and break off, leading to sharp pain in your feet or hands.

Ease the pain and protect your skin

If you suspect you’ve been injured by a sea urchin, the first thing to do is to leave the water and examine the affected area. If you see a spine poking into your skin, you can try to remove it — but do so carefully: Squeezing or tugging on the spine could cause it to break off and make its removal more difficult.

Wash the area gently, but avoid rubbing, which can push the spines in deeper. Instead, head to our clinic right away for professional removal. We can also inspect for signs of infection and provide antibiotics and other wound care as needed to ensure the area remains clean.

Watch for complications

If you decide to treat an urchin puncture injury on your own, keep a close eye on the area to watch for signs of potential complications. Worsening pain, swelling, redness, or drainage from the wound can all be signs of developing infection. 

If you start feeling faint, have trouble breathing, develop fever, or experience other severe symptoms, call 911 immediately.

Don’t take a chance on your health

Evaluating the severity of any type of injury on your own can be problematic, and what may seem like a minor issue could be masking something more dangerous. Many injuries benefit from professional cleaning, antibiotics, or vaccinations against pathogens like tetanus, and when medical care is delayed, complications can even become life-threatening.

If you’ve suffered an urchin puncture, coral scrape, or other wound, don’t put off medical care. Request an appointment online or over the phone with Minit Medical Urgent Care and Physical Therapy in Kihei, Kahului, and Lahaina, Hawaii, today.
