Here's what you should do if you are stung by a catfish:
* Seek immediate medical help: A doctor can assess the severity of the sting and provide appropriate treatment.
* Clean the wound: Gently clean the wound with soap and water.
* Apply a cold compress: This can help reduce swelling and pain.
* Elevate the affected limb: This can help to reduce swelling.
* Watch for signs of infection: If you experience any redness, swelling, pain, or pus, see a doctor immediately.
Note: Some catfish species have venomous spines that can cause severe pain, swelling, and even necrosis (tissue death).
It is crucial to get medical help as soon as possible following a catfish sting.
