Calling all nasty-rash experts

[chrislo09]

I just had a rash just like this after swimming in a pond in Hamakua. I found out there is an introduced species of plant called rubbervine. It gives you a rash very similar to poison ivy or oak. There is no cure, but maybe he accidentally touched this plant as I did. My rash took nearly a month to completely go away. My symptoms were identical to the ones you mentioned.
