I'm always sore, but that's to be expected <img src="/forums/images/graemlins/smile.gif" alt="" />
I too get fried airways and sinuses, and I've concluded it's because they get severely dried out in high altitude/low humidity and don't begin to heal until I get home to sea level.

I'll use saline nasal spray in the mountains and back home to reduce the symptoms, but it only lessens the symptoms.

The other thing is I have a hard time sleeping through the night when I get home, which seems counterintuitive considering the comfy bed and no bears skulking about the yard.
