Before my diagnosis I struggled with thick drainage down my throat. Once I got my lung congestion under control with daily airway clearance I could tell the drainage from my sinuses was a huge part of the problem in my lungs. I have a great ENT who has worked with me to try to figure this out. I have a Sjögren’s syndrome diagnosis so I cannot use antihistamines regularly. Allergy shots did not seem to work. Flonase slowed the drainage but not enough. Sinus surgery corrected some anatomical issues. Finally we tried Budesonide using a sinustar nebulizer cup. This is held under the nostrils. It takes about 7 minutes to nebulize and the thick stuff is gone for the day. If my allergies are particularly bad I can do it twice a day. This has been a game changer for me.
