2 yrs. ago I was in S.P. by Wet willys laying on a raft at the end of the dock where all the kids swim & a purple Man O War rolled up on my arm, it was clear & blueish in color with a sac, my arm was on fire & it left 5-6 tenacles on my upper arm, the pain shot down to my lower back & I could hardly move.
I was helped to the clinic & the pain was unbearable so they put me on Morphine, spent 3 hrs. there & was given some type of steroids to help the healing. I had a tatoo for about 4 months.
Doctor said it was a Purple Man O War.
It was the worst pain I ever experienced.
