About 3 weeks of cold/flu symptoms treated only with DayQuil and Afrin. Mostly nasal and some coughing. After the third week it got little better and then it hit again with double strength. No sinus infection (took X ray), no sore throat, no fever. Constant runny nose for a week, that turned into extreme stuffy nose. Sinus pressure, no pain. Headache and faster heartbeat. After 5 days on Z pack 250 mg with slight improvement was prescribed an extra 3 day dose 500 mg. I was also prescribed Medrol tablets.
