Have had throat congestion 24/7 for at least 5 years. Been to 2 ENT drs, 2 allergy drs, pulmonary dr and no one seems to know how to cure it. Have had tons of nasal sprays, no good, and that is all I get from them, Can't stand this day in and day out with many nights up because of this problem. I use Mucenex. allergy tabs, nasal congestion tabs, nothing works.
