I have had this problem as long as I can remember. Whenever I do any
cardio activity it happens, but it's much more of a problem when
running and when outside where it's colder.

I just went running today and I had to drain my nose (covering one
nostril and blowing to drain the other one) probably 5 or 6 times and
spit at least 50 times. It's incredibly irritating and it makes
running even harder than it already is for a person with pectus
excavatum (caved in chest).

My doctor told me it was caused by the air (often cold air) I am
breathing in so rapidly and to use Sudafed Nasal Decongestant to help
it, but it didn't make much of a difference.

Are there any solutions to this problem? Over the counter drugs,
prescription drugs, home rememdies...I'll try whatever.

If you find a solution that significantly makes a difference, I'll tip
you the max allowed amount. No joke. It means that much to me.

If you need any further information, please let me know.

I found no miracle cures, I'm afraid, but the following web page seems
to bear directly on your complaint, giving a clear and concise
explanation of the underlying physiological mechanism.

American Running: Runny Nose

The European nasal spray sounds enticing, but who knows when it will
arrive on our shores? I don't know if I would use it myself. I do find
myself horking and spitting at a greater rate than usual when I go
running, especially in cold weather, but I figure it's just nature's
way.

Interesting, I wonder when that was written. I'd like to try that
drying medication.

The only difference I see between myself and the person with the
question on that website is that my nose doesn't get drippy with a
clear watery liquid. It's very thick and stringy and it gets hard to
clear my throat, especially while trying to run.

Thanks!
