Have chronic cough need cateract surgery will take ativaan for anxiety but this won'the help if i start coughing?

Determine cause: Chronic cough is most commonly due to 3 conditions: asthma, post-nasal drip, or GERD (heartburn). You might have one or a combination of all three. Post-viral cough is also very common and can last for weeks. Further workup by Allergist is helpful as they can perform a more detailed assessment including skin testing, pulmonary function testing, etc. Treatment will depend on cause.
