Sorry to hear that you suffer from the same. Unfortunately I haven't found a fix yet so I keep searching. Asked for a referral to a more specialized ENT last week when I saw my ENT who doesn't know what to try anymore. So I'll wait for my new appointment and continue my search for a solution. The only thing that gives me temporary relief is nasal rinse twice a day with xylitol/salt mixture. It's just to flush the mucus out so it takes a while again to build up. But it's still terrible. If you find anything that helps, please share as well 🙂
