I have had a sinus blockage for years. I do not suspect swollen sinuses or sinusitis because when I lay down the drainage runs to the downward sinus leaving the anterior sinus free and clear. When I turn over, the same thing happens on the other side showing that the upward sinus is unobstructed. Lately my salivary glands have become swollen as well. I visited an ENT and was sen to get an MRI which was not dispositive and turned out to be expensive and useless. At that point the ENT wanted to surgically remove all salivary glands without even having diagnosed the problem or taking a needle biopsy. This seemed strange to me and unwarranted absent any confirmation. Are the two conditions related and what should I do?
