Hi Jacqueline-The welts can last up to a month, but they dont stay really bad that long. Mine lasted about 2 weeks. I got mine from the hydoids by hanging onto dead coral at Baracuda filming the Eagle rays. Otherwise I have received stings by getting too close shooting pics at something. I have used several 'rememdies' from the med thread here. But in answer to your question I did use some remedies that did alleviate the issue of ichiness not redness.
And a word about 'touching animals underwater, please dont do that, it does harm to them by doing these 'innocent' touches. Not to mention we can get hurt ourselves from it as you have observed. But I hope you had a good time on Coz, it's my fav. Also welcome to the board!
In addition to the advice above about seeking professional, knowledgeable help, I'd like to add;
DON'T PET THE CREATURES!
Nothing good (for the creature) can come from it and it can cause problems for the creature and you.
I hope your encounter resolves soon and you get back out there diving.
