This sting occurred on the beach at Cha-Am, Thailand and is typical insofar as the unsuspecting victim suffered intense pain and fear coupled with unfathomable incompetence from a medical professional who simply should have done better.
The incident took place in September 2008 and while it is cold comfort to this victim who today carries horrible scars, thankfully due to a dedicated team effort in Thailand there have been ongoing improvements in medical knowledge and training that hopefully will avoid this kind of outcome in the future - though there remains a long way to go.
Something like that endured by this poor woman could have been avoided by wearing a lycra suit - even just a long sleeve rashie top like those commonly worn across Australia that are readily available. A full length suit obviously provides better protection with legs being particularly vulnerable.
Also having a bottle of vinegar with you at the beach is a cheap investment in safety that is the first line of defence against a jellyfish sting - splash it liberally over the sting area for at least 30 seconds to stop the jellyfish tentacle from injecting more potentially lethal venom.
