Jellyfish are very common during the summer months along the Mediterranean coast. Therefore treatment of jellyfish stings is quite important.
On contact with humans, they will deliver a sting which is described as similar to an electrical discharge. Some can be quite nasty and will be followed by a strong stinging sensation around the contact area and varying levels of localised pain.
On being stung, seek first aid in situ from the nearest lifeguard or beach medical unit.
Although antidotes are available the best thing is to apply a cold compress to the affected area but never directly onto the wound, usually ice wrapped in plastic. This will eventually cause the pain to subside.
Although itchiness will occur, avoid scratching the wound. Avoid the use of cloths or towels to rub the area affected as this will aggravate the sensation. Thoroughly wash the wound with sea water not fresh water and then apply some antihistamine cream.
Should first aid not be available, the use of vinegar or urine to treat the wound are favoured local remedies.
Beach lifeguards are always on the lookout for jellyfish and if in doubt consult them.
