I think i have a congestion flu, as i cant stop coughing for the last 5 days.. but the coughs usually feel like mucus in the throat... i had my humidifier running all night and the coughing was non-stop but no pain... i have been taking Robutussin DM. And that seems to help.. but i have no fever, no body aches, lots of sinus headaches, and chest congestion.. im wondering if besides the coughing could this be worse. or just congestion.. if so besides robutssin dm and humidifer is there any way i can stop it fast thats not maoi..
