Stung by a jellyfish

Aug.4-7 2019: I was in water just before 9am in front of the Royal Lahaina. I was not that deep when I felt a stinging, burning feeling on my right arm. I did not see the creature, only the tentacles. At first I thought it was string or plastic, it looked like transparent linguine. I can share photos. Two days later when I got the nerve up to go back in the water, a little south of where I was stung in front of the El Dorado(@10am)...a little boy was stung on his foot as he sat playing in the sand, they said it was a bluish color so I’m not sure if it was a jellyfish. Two other women were stung, but they were all minor stings compared to my reaction. One woman said she saw small box jellyfish.
