My husband's nose is constantly stuffed up and he can hardly sleep at night. What can we do? His nose sometimes gets a bit clearer, but it's often stuffed up. He can't breathe through his nose at night and that means he doesn't sleep well because he snore
I would recommend that you see your local primary care provider, allergist or ENT provider. There are many reasons for having a stuffy nose (allergies, cold/sinus infection, polyps, deviated septum etc).
Saline irrigations, decongestants (oral and nasal), antihistamines are over-the-counter products that can be tried.
