The flu- we’ve all had it. But is it really what people think it is? Much of the time, when people think they have the flu, they are actually suffering from food poisoning of some sort. Nausea, vomiting, and diarrhea are not typical symptoms of the flu.
In fact, the usual symptoms include a sudden fever, coughing, head and muscle aches, joint pain, nasal congestion, and a sore throat. Still, these symptoms can be mistaken for a cold virus, as well. The only way to know if it is indeed the flu is to see the doctor within 2 to 3 days of the start of the illness.
