Getting stung by a jellyfish is not a pleasant experience. Even less pleasant is having someone insist that urine is a great cure for the sting. Believe me there are cleaner and more effective ways of dealing with it.
The first thing to do is to rinse the skin with hot water. If hot water is not available then use salt water. Using gloves, peel off the tentacles. If you don’t have gloves available then use a stick or shell. Avoid touching or getting them on your clothing.
Watch the victim carefully for anaphylactic shock. Symptoms can include itching, wheezing and dizziness.
If the patient can cope, immerse the wounded area into hottest water that they can stand. Preferably over 102 degrees. Give them ibuprofen to help with the pain.
Always seek medical attention if the sting was severe or if the victim is showing any signs of distress.
