I have ahistory of terrible allergies and sinus problems. I get PND, headaches, sinus pressure, itchy eyes, irritated throat, etc.
A couple time this year, I also have had a "crackling" or congested feeling in the lungs, as if gunk is in there. I can hear it frothing around when I breathe at night, especially in bed. One cough will clear it, and I havne't had any issues with shortness of breath (I run every other day).
The first time this happened I was sick with bronchitis, but it happened again last night, and the only thing bothering me right now is allergies.
Can it be allergies?
