After seeing many doctors for the same issue it is becoming increasingly annoying to have the same symptoms present. I am a 14 y.o. male swimmer.
I continually find a need for clearing my throat, as if something is caught there and I manage to bring up a lot of phlegm, which is quite watery. As well as this, when lying in bed it sounds as though occasionally something is actually dripping down the back of my throat. I am assuming this is post-nasal drip. I also have difficulty breathing when exercising even though I am extremely fit as a competitive swimmer. Also, I can be very tired at times, even though I get at least 8 hours sleep a night. Upon a few occasions I have had a swollen face for a day or two and it happens for unknown reasons. The doctors always seem to focus on asthma because of breathing difficulties but the tests come back normal or higher than normal due to my fitness from swimming. I have had a few viral infections of tonsillitis in the past few years as well as various other viral infections. I have also had a few migranes (not diagnosed).
Tests I have had are a chest x-ray, spirometry test, lung function test, blood tests and a sputum culture. All have been within a normal range.
I am wondering if anyone could advise me on whether this could be a case of CHRONIC SINUSITIS? The symptoms seem to fit and it seems to be one of the only things possible which hasn't been looked into.
