What to do if i have headache, fever, runny nose, cough?

Viral infection: Your symptoms are classical for an upper respiratory tract viral infection. These infections require your own innate immunity to resolve the symptoms. Over the counter nasal spray for 3 days only and a decongestant or cough meds for no more than 10 days can be suggested. If the symptoms do not disappear in 2-3 weeks or get worse, please consult your physician.
