Only a person who suffers from the stomach flu symptoms, or passed through it in life, knows what kind of pain it is, and how hard it is to fight with them in those days.
The worst thing that can happen to a infected person, is that in the course of the disease symptoms get a few symptoms at a time. This could, for example, mean that during episodes of vomiting, the person gets the urge for stool. Or vice versa, what happened in my case, that during episodes of diarrhea, gets the urge to vomit.
I really do not know which is worse of those two cases, but I am sure that the worst possible scenario would happen, if during the episode of diarrhea or vomiting a person got the urge to vomit or stool, and at the same time has symptoms of fever or headache.
So, now that we have listed some of the symptoms, which are definitely the worst, we can list the other symptoms that accompany stomach flu.
In addition to diarrhea and vomiting, fever and headache, there are more stomach flu symptoms, and those are: nausea, muscle aches, abdominal pain and cramps, chills, lethargy, fatigue and dizziness.
If you happen to have stomach flu symptoms for longer than ten days, and especially if they are frequent, you should contact your doctor for advice and establishing a diet, and also for further medical examinations.
Tip: Do not use any medicine to relieve symptoms, because they can only worsen your condition.
