Stepping on a Nail, Glass, or Fish Hook: Puncture Wounds in Arugam Bay

Barefoot is the default way of life in Arugam Bay — flip-flops off at the guesthouse, bare feet from breakfast to the lineup and back. Most days that’s fine. But the sandy paths, boat yards, and beach-front lots here hide a steady supply of rusty nails, broken glass, fish hooks, and the occasional stray piece of rebar from a half-finished building. We treat puncture wounds at the clinic year-round, and they catch people out because a small, deep hole looks far less alarming than it actually is.

Why a puncture wound is worse than it looks

A puncture wound is deceptive. The entry point is tiny, it stops bleeding fast, and within an hour you can barely tell it happened. But a nail or fish hook doesn’t just break the skin — it drives dirt, rust, and bacteria deep into the tissue and then reseals the surface over the top of it as you pull it out. Unlike a reef cut or a graze, which stays open to air and bleeds itself somewhat clean, a puncture wound closes over a contaminated tract with very little drainage. That combination — deep contamination, minimal bleeding, and a sealed opening — makes puncture wounds one of the highest infection risks we see, and the classic setup for tetanus.

The usual culprits around Arugam Bay:

• Rusty nails and screws, especially around construction sites, old fences, and boat yards
• Broken glass, often from bottles left on the beach or around bars
• Fish hooks, left behind by local fishermen or dropped from tackle boxes near the harbour
• Sea urchin spines and stingray barbs, which behave like punctures but need different first aid (see our separate guides on those)
• Bamboo splinters and sharp coral fragments on the beach paths

First aid for a puncture wound

1. Stop and check what caused it. If it was a nail, glass, or metal, try to establish whether any fragment broke off inside the wound. This matters more than almost anything else about the injury.
2. Let it bleed a little. Unlike a cut, gentle encouragement to bleed for a minute helps flush contamination out of the tract. Don’t squeeze hard, just don’t rush to stop it the way you would a larger wound.
3. Rinse thoroughly with clean water. Bottled or filtered water if you’re not near a tap. Seawater is not a disinfectant.
4. Do not dig around for a fragment yourself. If you can see something in the wound and it comes out easily with rinsing, fine. If it’s embedded, leave it and come to us — probing a deep puncture at home usually pushes debris in further rather than out.
5. Disinfect and cover loosely. Povidone-iodine or chlorhexidine on the skin around the opening, then a light dressing. Don’t seal it airtight; punctures do better with some airflow once the surface is clean.
6. Watch it closely for the next 48 hours. This is the window where a contaminated puncture turns into a real infection.

Come and see us if

• The object was rusty, dirty, or came from a boat yard, fence, or construction site
• You’re not sure whether something broke off inside
• The wound is on the sole of the foot, a joint, or the hand — all areas where infection spreads fast and does more damage
• It was a fish hook with a barb — these often need the hook pushed through and clipped rather than pulled back out, which is much easier for us to do properly than to attempt on the beach
• You haven’t had a tetanus booster in the last five to ten years, or you genuinely don’t know
• After a day or two you notice increasing pain (rather than decreasing), redness spreading outward, swelling, warmth, pus, or fever — these are infection, and punctures hide infection well since so little drains to the surface

Tetanus: the reason punctures get special attention

Tetanus bacteria live in soil, rust, and animal waste, and thrive specifically in the low-oxygen conditions of a deep, sealed puncture wound — exactly the environment a nail or fish hook creates. It’s rare, but it’s serious, and it’s entirely preventable with a booster. If your last tetanus shot was more than five years ago and the wound is dirty, or more than ten years ago regardless, come in for a booster. We stock tetanus vaccine and can give it the same visit, alongside cleaning the wound properly and starting antibiotics if the injury looks high risk. Bring your vaccination record if you have one — it saves us guessing.

Prevention

Wear sandals or reef boots on beach paths, boat yards, and anywhere near construction, even for a short walk. It’s the single easiest way to avoid this entire category of injury. If you’re fishing or handling tackle, keep hooks in a covered box rather than loose in a bag. And if you’re renting a room in an older guesthouse, a quick glance at the path to the beach in daylight tells you more than you’d think about where the nails and glass tend to collect.
