What to do if i have numbness in mouth after eating sushi?

Ciguatera?: numbness after eating sushi can be a symptom of several things, but one of them is ciguatera toxicity. It is found in reef fish, usually in the summertime. it causes lip and tongue numbness, 2-6 hours after eating, but can also cause nausea, vomiting, diarrhea, and abdominal pain, and cardiac and neurologic problems. If you are having these symptoms, go to the ER to be checked out. Good luck.
