How painful is getting stung by a jellyfish?

How do you avoid getting stung by a jellyfish?
Wear a protective suit. When swimming or diving in areas where jellyfish stings are possible, wear a wet suit or other protective clothing. Diving stores sell protective “skin suits” or “stinger suits” made of thin, high-tech fabric. Consider protective footwear as stings can also occur while wading in shallow water.
Do jellyfish die after they sting you?

Certain box jellyfish stings can kill a person within minutes. Other box jellyfish stings can lead to death in 4 to 48 hours after a sting due to “Irukandji syndrome.” This is a delayed reaction to the sting.
