Any ideas on a poison ivy type rash?

[nereas]

Hi,

Diving the Florida Mini Lobster season last week had me spending a lot of time scraping along the bottom, sand & rocks. I didn't wear a dive skin or wet suit and I'm now wishing I had! I got into fire coral a couple of times (ouch!) and something else that felt very similar.

Thing is, the stuff that was similar has turned into an itchy poison ivy type rash. It's itchy as hell!!! The rash is starting to subside, but I'd like to know what it was (or could have been) so I can avoid it next time. Anyone have any clues as to what organism causes this? BTW - I've never reacted to poison ivy...

Always, always, always wear at least dive skins. Then all you need to worry about in Florida is sea lice!

Never, ever, ever wear only a swimsuit or even a shorty.

Now, as it were, dont scratch because it could then get infected, and only then get worse!

Wear pajamas and sox at night, so that you dont scratch in your sleep.

My 2 Euro's worth.
