Spiderfish sting

Spiderfish bites are common on beaches and can cause intense pain. If you are stung by a spiderfish, the first thing you should do is look for a lifeguard. If you can't find one or there isn't one, it's important to follow the steps below to treat the sting properly:

  • Get out of the water: Get out of the water immediately to avoid further bites and to be able to treat the affected area.
  • Clean the wound: Wash the affected area with seawater to remove any traces of poison and sand. Avoid using fresh water at first, as it can increase the pain.
  • Hot water immersion: Immerse the affected area in hot (but not scalding) water at a temperature of around 40-45°C for 30 to 90 minutes. The heat helps to neutralise the poison and relieve pain. Test the temperature of the water with an unaffected part of your body to make sure it's not too hot.
  • Removing thorns: If thorns are visible, try to remove them with disinfected tweezers. If the thorns are deeply embedded, seek medical help.
  • Disinfection and Wound Care: After immersion in warm water, wash the area with mild soap and water and apply an antiseptic to prevent infection. Cover the wound with a clean, dry dressing.
  • Pain medication: Take over-the-counter painkillers such as paracetamol or ibuprofen to relieve pain. Always follow the dosage instructions on the packet.
  • Symptom Observation: Monitor the wound and look out for signs of infection, such as increased redness, swelling, local heat or the presence of pus. If you notice any of these signs, consult a doctor immediately.
  • Tetanus vaccination: Check that your tetanus vaccination is up to date. If not or if you have any doubts, seek medical attention for a possible booster vaccination.

 

When to seek medical help:

  • If the pain doesn't subside after the initial treatment.
  • If there are signs of infection or an allergic reaction, such as difficulty breathing, excessive swelling or a rash.
  • If you can't remove the thorns or if the wound looks deep.

 

By following these recommendations, you can treat spiderfish bites effectively and reduce the risk of complications.
