Do dead jellyfish poison you?

I went swimming sea Donghae in this vacation.

A jellyfish that died while swimming came near me.

Suddenly, the exposed parts of the face and clothing...
It started stinging, so I came out of the water.
It stings for a day or so.
It's not unbearable, it's disturbing.

I don't know if there's any toxic effect on a dead jellyfish.
I'm curious.

SO.

Dead jellyfish also poison the tentacles because they remain toxic.

While bathing in the sea, there are cases of stinging pain in submerged bodies such as arms, legs, and torso at some point, most of which are likely to have been stung by jellyfish. A jellyfish sting can cause stingy pain and whip-shaped red wounds. Jellyfish poisons usually have mild local reactions such as pain, skin rash, and edema, but if they are severe, whole-body reactions such as chills, muscle paralysis, dyspnea, and nerve paralysis should not be taken lightly.
