How recent was this training?Kris-I was just relaying what I learned in NOAA training and from UH dive office training. The world seems to be rather wishy washy on proper treatment with no one has offered a solution that everyone can agree on. It seems no matter what you do, it will hurt like hell for a bit, then a day later you might get little itchy bumps.
I do recall it was sometime in the past few years that DAN revised the MOW recommendations based on scientific studies as to how the nematocysts behave, as well as rates of infection due to use of non-medical agents (e.g. meat tenderizer).
Ultimately, you're right about the hurts like hell, then maybe itchy bumps -- the goal, however is minimize this. We won't eliminate it, but with any luck we can reduce the reaction and perhaps prevent possible anaphylactic shock.
