I have been coughing for a week now - It started with a scratchy throught, then progressed into lethargy and lots of deep unproductive coughing - never a runny nose, sneezing, or anything like that. It s a dry cough for the most part with pockets of phlegm releasing from time to time. I also experience a constant nagging headache. Last Sat/Sun I took mucunex dm, no results. Last Monday I started taking alkaselzer cold plus which resulted in one good blow of discolored mucus. Thought I was feeling better, but finished the package as of Thursday night. Lethargy and deep cough remain, often waking me up at night, making it difficult to get anything done or disturbing others around me. Since Thursday I have been taking Delsym cold/cough but it doesn t help either. I don t know what else to do. My rib cage, neck, throat, and head hurt from coughing so much and so hard. Any suggestions would be appreciated. Now my husband has begun having the same symptoms.
