I was in Hawaii last week and got stung by a very tiny blue jellyfish at Kailua Peach Park. After doing some research about this jellyfish, I believe it was the Man o' War jellyfish. I really didn't know what was going on, just felt weird like numbing on my wrist and i was the tentacle was still on my wrist. i just washed it away in the ocean. The pain went away after like 45 minutes. I thought it was ok. I didn't know that i have to wash it with vinager and meat tenderizer. After a week now, i have rash on my wrist, no pain but very itchy.
Any advice on this? Should I use the vinager and meat tenderizer now?
