Hello. This is my first time commenting on here. I'm a nurse with over 10 year of experience, and 2 of that working directly for ENT specialists. In addition, I am currently suffering from the same symptoms that many have mentioned. Symptoms: Daily mucus plug that is about the size of a full fingernail. It begins with swallowing excessive post-nasal drainage, the drainage builds up, then an irritated and stinging sensation, and finally it reaches a point when I know hacking once more will dislodge it. Once dislodged, it has a firm yet tacky texture with fresh mucus borders. Sometimes it has a scant amount of blood. I have a history of sinonasal surgeries to correct a deviated nasal septum and to open for proper drainage of the sinus cavities. Most recently, I went to my local ENT at Ohio State which is ranked #3 in the country for ENT. They performed a nasal endoscopy and found that I have a nasal perforation at the back base of the septum. He stated he believes that the back of the opening is acting as a dam, preventing the drainage from draining quick enough. This is backing up and allowing it time to dry and become tacky. They have recommended that the perforation be corrected to allow better drainage. Let me say this, it occurs worse in fall and winter (dry months). Note, these symptoms are different than those experiencing scabs in the nose, and different from those with COPD who cough up mucus plugs (this is a lung disorder). Those experiencing what I have would do well to use saline rinses that promote flushing out excess mucus. It is a drainage issue. Best of luck to everyone and may we all gain some relief soon.
