Hello.
Thank you for asking at HCM.
I went through your history and I think you have
cough due to both -
acid reflux (we call it GERD -
Gastroesophageal Reflux Disease) and post-nasal drip due to
sinusitis.
Were I to treat you, I would suggest you
omeprazole (or similar drug) before each meal for GERD for at least 6-8 weeks. Also, I would suggest you to avoid hot, spicy meals and eating too much at a time, especially in the evening. If possible, a relaxing brief walk after evening meal will also help.
Of you smoke, drink alcohol or consume excessive tea-coffees, please try to avoid them. If this does not apply to you, that is great!!
For sinus, I would advice you to take
montelukast and
levocetirizine for at least 2-4 weeks. I would also suggest daily irrigation of nasal cavities with nasal saline spray 3-4 times a day. I would also suggest you to avoid air pollution, dusts and smoke as much as possible. Daily steam inhalation and gargles with warm saline will also help if you are comfortable with it.
Since both GERD and sinus disease need a long treatment, patience and positive attitude will be help you a lot.
Hope this will be helpful to you.
Wish you the best of the health.
Regards.
