I use cheap saline nose drops to seriously reduce pollen allergies causing clogged sinuses. Clogged sinuses get infected by cold virus causing post nasal drip in throat. That results in lung infection and cough. Nasal drops are less than $3 at Walmart.
I have allergies to house dust, cool weather mold, ragweed, and cigarette smoke, so I have nasal congestion and puffy under eye area problems almost always. I can keep the nasal congestion under control by using 6 to 8 grams a day of Vitamin C. One or 2 grams morning and bedtime, and 1 or 2 during the day anytime my nose gets stuffed up or drippy. Always before I stir up dust by housecleaning. However the Vitamin C has no effect on the puffy under eye issue. Has anyone successfully tried that cream advertised on TV that makes your puffiness disappear when applied lightly to the skin under the eye?
