4. Fever
Another sign that you may have food poisoning is that you begin running a fever. Typically, if food poisoning is the culprit the fever will be low grade and not cause too many issues. A fever is simply the body trying to get rid of whatever is causing distress in the body. The body uses a fever to help fight off infections. If your fever starts to get high it is a good idea to try a pain reliever/fever reducer to take.
This can help keep your fever down and may help with some of the other issues that are being caused by food poisoning. It is important to note that if you start running a fever that is steadily increasing and gets higher than 103 degrees Fahrenheit, you need to get to a doctor as soon as possible. Running a high fever for too long can cause the body further distress.
