6. Analysis of Frequently Asked Questions

The source material addresses several common questions, providing key clarifications on jellyfish stings.

• When to See a Doctor: Immediate medical help is necessary for any systemic symptoms (e.g., breathing difficulty, chest pain, dizziness, loss of consciousness), if a child or elderly person is stung, if the sting is on the face, eyes, or throat, if symptoms progressively worsen, or if a large portion of the body is affected.
• Permanence of Marks: Jellyfish sting marks are generally not permanent. In mild to moderate cases, the redness and welts typically fade within a few days, and the linear marks disappear within one to two weeks. Deep, severe stings can rarely result in scarring.
• Lethality of Stings: While most jellyfish stings are not fatal, certain species pose a deadly risk. The Box Jellyfish is considered the world’s most venomous and can cause heart failure and death if not treated promptly.
• Causes of Post-Swim Itching: Itching after being in the sea can be caused by several factors, including minor stings from microscopic jellyfish tentacle fragments floating in the water, contact with “sea lice” (planktonic jellyfish larvae), or skin irritation and dryness from saltwater.
