6. Chills
Being sick with anything is really not a fun experience. Food poisoning can cause many unpleasant symptoms as you can see from this list. While some people develop a fever and become too hot, other people will have the chills off and on while the body is trying to get rid of whatever you ate that caused this to occur. Most often, a person will have a fever and then when it starts to break, will develop chills.
The back and forth between fever and chills can go on for quite a while. Once again, these symptoms can be anywhere from mild to severe. If you have a high fever you need to see a doctor. If you develop chills, try to stay warm in any way that you can. Your body is doing everything that it can to get rid of the bad bacteria or the virus that is upsetting your system.
