Runny nose, cough wet. Headache with green/yellow mucus in nose & coughed up. Pressure around nose. Worse after a wk. & cough worse at night? Flu?

Respiratory infx. You should get evaluated to see what treatments would be best for what sounds like an upper respiratory infection/sinusitis and possible bronchitis. With influenza you typically get a cough, fever, chills, body aches so I don't think you have influenza.
