I got nausea after eating. i know it could be food poison because it probably wasn't fully cooked. the question is: how should i treat nausea and would food poison harm me?

It is not called food poisoning for kicks of course I could hurt you. Time will tail avoid eating uncooked food check with your doctor

Depending on the type of food poisoning, different steps may need to be taken. For all of these, drink enough water, Gatorade of an electrolyte drink to stay hydrated. In most cases the symptoms subside in a day or so. If the symptoms last longer, it would be prudent to see a doctor.
