Jellyfish sting treatment in Patong
One moment you are swimming off Patong Beach, the next there is a burning line across your arm or leg that feels like a whip. Jellyfish stings are common along this coast, especially in the rainy season when currents push more of them inshore. Jellyfish sting treatment in Patong is available at our clinic 24 hours a day, and what you do in the first few minutes matters.
What to do straight away
Get out of the water calmly. Rinse the area with plenty of seawater, not fresh water. This is the part people get wrong: fresh water changes the pressure balance and makes any remaining stinging cells fire, which makes the pain worse.
Do not rub the area, do not scrape it with sand, and do not use ice directly. If you can see tentacle pieces, lift them off with tweezers or a gloved hand rather than bare fingers. Vinegar helps with some species and is often kept at beach first aid points.
Then come in, particularly if the sting covers a large area, if it is on the face or genitals, or if you feel unwell in yourself.
When a sting is an emergency
Most stings here are painful rather than dangerous, but not all. Call an ambulance or get to hospital immediately if there is difficulty breathing, chest tightness, swelling of the lips or tongue, severe muscle cramps, vomiting, confusion, or collapse.
Box jellyfish are present in Thai waters, though encounters are rare. Their stings cause severe pain very quickly and can affect the heart and breathing. Treat any sting followed by feeling systemically unwell as urgent, not as bad luck.
How we treat it
The doctor examines the area, removes anything still embedded in the skin, and treats the pain properly, which often means more than a paracetamol. Hot water immersion helps with several species, since heat breaks down the venom, and we use it where it suits the sting.
We give antihistamines and steroids for the skin reaction, and treat the wound to prevent infection. Broken skin in tropical seawater gets infected easily, so this is not a cosmetic concern.
The rash that comes back
Some people get a delayed reaction days after the sting, with the pattern of the tentacle reappearing as an itchy, raised rash. It is confusing, and it is a normal immune response rather than a new sting. It responds to steroid cream and antihistamines, so come back rather than assuming something has gone wrong.
Sea lice and smaller stings
Not every sting comes from a visible jellyfish. Sea lice, which are tiny jellyfish larvae, cause an itchy rash under swimwear where they get trapped against the skin. It appears hours later and catches people out. Rinsing and changing out of swimwear promptly reduces it, and we can treat the itch when it has already taken hold.
Scars and skin marks
Sting marks can leave darker lines on the skin for weeks or months, particularly if the area is then exposed to sun. Keep it covered and use high-factor sunscreen once healed. We will tell you honestly what to expect.
Common questions about jellyfish stings in Patong
Should I use vinegar?
It helps for some species and is widely recommended at Thai beaches. It is not a treatment for the pain, so come in if it is severe.
Is urine really a treatment?
No. It is a persistent myth, it does not help, and it can make things worse. Use seawater.
How long does the pain last?
Sharp pain usually eases within a few hours. Itching and skin marks can last days to weeks.
How much does treatment cost?
It depends on the severity and whether injections are needed. Message us for a quote.
Can a doctor come to my hotel?
Yes, for mild and moderate stings. For breathing problems or collapse, call an ambulance.
