I have constant coughing and an extreme amount of mucus. The cough doesn t go away. It gets to the point I cough non stop and start gagging, my chest and back hurt from coughing, I have severe shortness of breath and wheezing. I have been treated for chronic bronchitis several times. As, they think that is what it might be. They put me on prednisone (sp), breathing treatment, steroid shot and singular. It does help tremendously and it practically goes away. But within 3-4 months I start getting all stuffed up again and the coughing and mucus come back. Is there a possibility it could be something else. Thyroid, TB, celiac (sp)
