Jellyfish usually appear on the beach, especially on the Mediterranean coast, when the temperature is high and after a winter with little rain, as has happened this year. It is very easy for people who bathe to suffer jellyfish stings when these animals are near the shore, because it is enough to rub against them to suffer the consequences, in the form of a sharp and annoying stinging.

The best way to treat jellyfish bites and reduce the discomfort they cause is to wash the wound with saltwater, and apply cold compresses to reduce pain and an ointment containing antihistamine and corticosteroids to alleviate inflammation. Experts advise against the use of some popular resources, such as pouring urine or fresh water on the wound or covering it with sand, as this would only contribute to spreading the toxin inoculated by the jellyfish, and could even aggravate the rash.

In the event that any tentacle of the jellyfish has become attached to the skin, it must be removed, but always using gloves to avoid coming into contact with it. Pouring a little vinegar can help to detach it from the skin more easily.

Although the presence of banks of jellyfish near the beach causes great alarm, the rash that causes the bite of these animals, and that is due to a toxic substance they have in the tentacles, is not serious; however, some people may suffer an anaphylactic shock due to an allergic reaction to the toxic substance.

The main symptoms caused by the jellyfish sting are pain and itching in the affected area, and hives on the skin. The pain is quite intense, usually lasts between 30 and 60 minutes, and if it lasts it is advisable to go to a medical center to prevent the onset of an anaphylactic shock. The bites can also be dangerous for especially vulnerable groups such as babies -Whose immune system has not yet matured-, and the elderly, especially if they suffer from cardiovascular diseases or continue medical treatment with several drugs.
