I have had this stuck feeling in my throat for about 5 years now and have been to several ENT docs and none of them can diagnose what l'm feeling. I believe it is stuck mucus that won't go down or up but last night I had a break through. I spent some time in the sauna and then took a shower and while blowing my nose a black substance came from my throat. I felt a little relief after wards and I'm certain it's part of what l've been feeling for the last few years. For context I smoke. How can I get the rest of this thing out ? Do I have to stay in the sauna and then cough it all up? Is there a better way?
