I have been sick for 5 days. It started with a dry cough that hurt my throat and chest. Then for 3 days it was mild fever, chills, runny nose, slight cough, aching legs and hips, no energy, no appetite, and watery stools. Today I have had no fever, no chills but, still alittle snotty with a deep non stop cough. I am starting to gain my energy and appetite back as well. Does this sound like flu?
