If you are stung by a jellyfish, stay calm. Immediately you will feel the sting. Depending on your pain threshold the sting can last up to 30 minutes and it’s common for the pain to travel to your lymph nodes. To remove the stingers (or tentacles of the jellyfish) use the very tips of your fingers, where the skin is tough, to scrape them off your skin.
Take care to not touch your face or skin as the stinger could stay stuck on your finger.
Get to the nearest shower and pour warm water over the stings.
Alert the lifeguards so they can let other swimmers know.
