i know you believe the problem is sinus drainage but has anyone evaluated you for acid reflux? i mention this because people (especially those with sinus problems) often believe they are constantly coughing up nasal drainage when actually they're coughing up stomach acid. you can test this theory yourself by taking an over-the-counter antacid for a few days to see if it helps the problem. a lot of people aren't aware stomach acid can move all the way up the esophagus into the posterior portion of the mouth (especially when sleeping). sometimes acid reflux is actually diagnosed by a dentist who notices substantial erosion of the molars caused by stomach acid. if the antacid helps or if you can correlate a pattern of "phlegm" with food intake you might take up the acid reflux idea with your health care provider during your next visit. wishing you well!
constant phlegm in throat. a few years ago (age 16) i had an adenoidectomy due to it being large and the dr thought it was causing my problem (of having a blocked up nose 24/7). all this achieved was that now the mucus drips to my throat for me to cough it up rather than going to my nose. had 2nd adenoidectomy to remove the remains no change. . seen countless drs and none know what's wrong with me. i've taken cetirizine lots of nose drops/sprays nothing has helped. can anyone give me a new idea of how to fix this? . thanks . stu
