I use warm chicken broth to help bring up my mucus. It doesn’t taste half bad either; I look forward to it every morning now. Used to use warm water with lemon.

Hi Tina. This was very annoying for me until I figured out how to use it to my advantage. Did it just start happening since you found out about COPD?
IT doesn't have anything to do with our breathing, but can help US know when something else is going on.
Here's my version: Post-nasal drip is caused by (many) things like allergies, dry air and occasional infections. Dry air causes the blood vessels to swell in the nose to bring in MORE moisture. If the extra mucus is allowed to drain down it could create a bed for infections. The cure is to keep the nose moist with simple nasal sprays. I use sprays during the day and all hours of the night. Keeping the nose as clear as possible I can focus on how the lungs are doing without the distraction. When you see your Doc she may just throw a medicated spray at you and hopes it may help. But it is better if you understand the process for yourself. Take a look here:

In general, our breathing keeps us more dried out more than others and we need to stay hydrated at all costs. The extra bathroom runs even count as exercize. Take care.

NeilMed, which has netti pots for sinus rinse, also offers squeeze bottles for the same purpose. I find them easier and faster to use and just as effective at getting junk out of my sinus cavities. It is a bit like getting water up your nose when you were a kid in the swimming pool, but it does clean things out and if you use a solution of salt and baking soda or the packets they sell, it's not nearly as painful. Pre-Covid, I traveled a lot by air, and used the solution to clean out my sinuses after I got to my destination. I rarely got sick and I think a lot of the reason was using the sinus rinse.

(Email address can only be seen by the question and answer creators) you for the very informative article article!
I’ve tried a Netty Pot, but just don’t like the sensation.
I also used to use Flonase, but started having frequent nose bleeds. I’ve avoided using it unless my allergies are really bad. I’ve seen saline and moisture solutions on the pharmacy shelf but really hadn’t thought of using them.
Great input, friends….that’s why I love this forum🙋‍♀️👏👏

I have frequent sinus trouble. My doctor prescribed Flonase nasal spray. I also take cetirizine but maybe that is what would affect your bp.
