Stings from marine animals are relatively common, especially during the swimming season. In most cases, there is no need to go to the hospital, but sometimes it is the best option. Therefore, it’s important to know what to do if you get stung by one of these creatures.
Some characteristics to consider:
- The Portuguese Man o' War floats on the surface of the water and belongs to the jellyfish family. It has a blue/pink gas-filled sac, and its sting is very painful.
- Jellyfish have long, thin tentacles covered with small venomous suckers that cause burning sensations. They can move at various depths.
- The stonefish camouflages itself in the sand. It has venomous spines on its dorsal region and gills.
What are the most common symptoms?
- Pain or burning
- Itching and tingling
- Swelling and redness
What are the less common symptoms?
- Breathing difficulties and chest pain
- Blisters on the skin
- Nausea and vomiting
- Persistent fever
What should you do if stung by a marine animal?
- Leave the area where you were stung.
- Remove any spines or tentacles that may have stuck to your skin using a glove or a piece of clothing. Do not touch the spines or tentacles directly with your hands.
- Wash the wound with plenty of seawater, not fresh water.
- Immerse the affected area in very hot water for about 30 minutes.
- Take a painkiller (such as paracetamol or ibuprofen) to relieve pain.
- If pain persists after these steps, seek medical help.
What should you never do?
- Apply ice
- Apply urine to the wound
- Cover the wound
- Use sprays such as topical anaesthetics
- Touch the spines/tentacles directly with your hands
The use of vinegar is not appropriate in all situations. In the case of a jellyfish sting, vinegar can help, but for a Portuguese Man o' War sting, it is not suitable.
Go to the hospital if:
- You experience fever, chills, chest pain, breathing difficulties, vomiting, or dizziness
- You faint or have severe bleeding
- There is significant swelling around the wound
- The sting is on the genital area or face
- The pain is intense and doesn’t subside or decrease with conventional medication
Precautions to avoid marine animal stings:
- Never touch these animals, even if they appear dead, as they may still contain venom
- Check for warning signs on beaches
- Wear water shoes if walking in the shallows, for example
- Always supervise children.
