7.Fatigue
Feeling like you have no energy or appetite is a typical symptom of the flu — it’s less often caused by a cold. It can also be a sign of pneumonia or a sinus infection, which is common but more serious than a cold.
8.Sore Throat
A mild one is a typical symptom of a cold and sometimes the flu. It should clear up once your cold or flu does. But a very painful sore throat that comes on quickly can be a sign of strep throat. That’s a bacterial infection that should be treated with antibiotics.
