I have regular throat clearing, cough and cold analysed as a post nasal drip. how do i deal with it as it irritates me the whole day since 2 years?

Post nasal drip: Post nasal drip can be onry. Allergies is a common cause of post nasal drip. Acid reflux is less common but is a possible one. If you know the cause, it is easier to treat than if you don't. I find nasal rinses to be helpful in case of allergies, chronic or acute sinusitis. I like to use neti pot. Sometimes nasal sprays (flonase for example) can be helpful. Discuss this with your doc.
