Ideal,
It may still be your sinuses anyway. Sometimes that will happen to me, when my head hurts (pressure and that "I can't pick my head up because it's so heavy" feeling) and I can still breathe. The sounds in your chest, that may actually be drainage from your sinus areas (your nose) that's going down there and causing you to be congested and stuff. You can get an RX for that instead of OTC products, which I've found cause you to get either sleepy or spacey.
I think you should go to an allergist and have them help you. You don't need a CT-scan. I went it was the best thing I ever did. I am a much happier person taking Allegra every day
Always in Service...
