NHS 24 Medical Director Professor George Crooks said: “If you are unfortunate enough to be stung, most jellyfish stings are mild and don’t require treatment, or you can treat them yourself.

“Any remaining tentacles should be removed using tweezers or a clean stick (wear gloves if they’re available). Applying an ice pack to the affected area will help reduce pain and inflammation. After a jellyfish sting, any pain and swelling can be treated with painkillers, such as paracetamol and ibuprofen.

“Remember that vinegar is no longer recommended for treating jellyfish stings because it may make things worse by activating unfired stinging cells. The use of other substances, such as alcohol and baking soda, should also be avoided. Applying shaving cream to the affected area will help prevent the spread of toxins.” He added: “The best prevention is to try and avoid jellyfish. If you are walking along the beach, be careful not to touch jellyfish that have been washed onto the shore. They can still be venomous so try to keep curious kids and dogs away from them.”
