Flu Calves Sore What Are The Flu Symptoms?

What are the flu symptoms? - flu calves sore

I never had the flu before ... but I wonder what they are and what is typical of the presence in it?
Last week, on Tuesday morning I had stomach pain, diarrhea and loss of appetite. My stomach is still not satisfied, but better ... but now I have a pain in the muscles of the thighs, buttocks and calves. I woke up this morning with a sore throat (but) not stuffy. I do not think I have a fever .. But I have a headache today and I drank my fluids.
It sounds like the flu? I am completely incapable ... You still have some energy.
