Jellyfish Sting: First Aid That Actually Works

Jellyfish arrive on the Costa del Sol every summer, and sooner or later most beach regulars get brushed by one. The good news: with the right first aid, the vast majority of stings are painful but harmless. The bad news: almost everything people traditionally do on the beach makes it worse.

What should I do straight away?

• Leave the water calmly. Panicked swimming raises your heart rate and spreads discomfort; a steady exit is safer.
• Rinse only with sea water or saline. Never fresh water — it triggers the stinging cells still on your skin and injects more venom.
• Remove tentacle fragments without rubbing. Use tweezers or the edge of a bank card to lift them off. Never wipe with a towel or your bare hand.
• Apply local cold for 5–15 minutes using a bag of cold water or wrapped ice. Do not put ice directly on the skin.
• Take a painkiller such as paracetamol if you need it.

What should I never do?

• Fresh water — the number one mistake, for the reason above.
• Rubbing with sand — it drives the stinging cells deeper into the skin.
• Urine — a myth. It does not help and can make things worse.
• Ammonia or alcohol — they irritate the skin further.
• Scratching — tempting once the itch starts, but it prolongs the reaction and risks infection.

What is that jellyfish that looks like a fried egg?

If you see a round jellyfish with a raised yellow dome in the middle — genuinely like a fried egg floating in the sea — that is the fried egg jellyfish (Cotylorhiza tuberculata). It is extremely common in the Mediterranean in late summer.

Its sting is mild compared with other species, and swimming near one is rarely a problem. But do not touch it, in the water or washed up on the sand: it can still irritate the skin, and children find them irresistibly poke-able.

How long does a jellyfish sting last?

The sharp burning usually settles within a few hours. Redness, itching and whip-like marks on the skin can last several days and sometimes flare briefly again. A soothing cream and not scratching are usually all you need — ask us and we will recommend one suited to your skin.

When should I see a doctor or call 112?

Seek urgent help if:

• A large area of skin is affected.
• The sting involves the face or eyes.
• There are systemic symptoms: dizziness, nausea, breathing difficulty, chest tightness.
• The person has a known allergy to stings.
• The reaction worsens over the following days instead of fading.
