Dr put me on codiene cough syrup to help calm down my cough and its not helping still up at night coughing head still feels full have sinus pressure?

Cough: Sounds like a viral illness with bronchitis and sinus issues. The cough in bronchitis can go on for a month. if its persistent you should get a chest xray and make sure you dont have pneumonia. You might need antibiotics. For the sinus part, steam, saline sprays and OTC decongestants help ( dont take them late or you will be up all night)
