This a.m I was surfing at turtles and landed with my foot on a cobbler that was resting i guess in between all the seaweed, I kept surfing for a while until i get out of the water and start to hurt like hell, lucky am close by, still attach to the hot water bucket and is being 5 hrs since then.... I wonder how long am gonna be stuck to it ? 
Ouch they hurt like hell i hear. I have a mate who got done awhile ago and he is super tuff. But couldn't stand the pain and poured boiling water on his foot. He said the 1st degree burns were even better
Get to a hospital. Mate and i were cobbler spearin and he stood on one. Got given some serious pain killers and was of with the fairys for the rest of the night. Hurt like hell to they gave him a jab.
Well, after nearly 6 and a half hrs and lots of buckets of hot water the pain vanished. What a relief ! 
Get yourself a heat pack which you can microwave, much more portable than a bucket of water and easier to control the heat so you don't end up in hospital with a bad scold.
You can also get air activated self adhesive heat packs which you can stick to your foot and wear a work boot over.
5 cobbler stings to date and still counting.
Thanks guy's appreciated your comments, i will get some of those heat packs you mention it might be a good idea to have them handy just in case. 
Pardon my ignorance Whats a cobbler?
Not a stingray by any chance ? Have experience with one of those
Ouch - sounds painful.
