Hi, I have had laryngitis for 3 days. I have been taking alka seltzer cold and cough around the clock. I also have some chest congestion and have coughed up some green/yellow stuff. I have also been gargling warm salt water on the hour for 3 DAYS. My question is how much longer should I wait before I seek additional help? I don t really feel bad, I have been very sleepy and I cannot talk at all.
