I have a prolonged cough after 8 days of the flu. No fever, non productive, dry cough. No sore throat, dysphagia or sputum. I took a course of Tamiflu with no relief. The only relief I get is if I lean forward at about a 45 degree angle which helps alleviate the coughing.
HI, thanks for using Chat Doctor Unfortunately the cough following a viral infection can last up to 6 weeks even after all the other symptoms have resolved. This is called post viral or infectious cough. It may be due to persisting inflammation in the chest. The use of over the counter cough and cold medications may be helpful. I hope this helps
