Welcome to Healthcaremagic.
Hi, I am Dr Anshul Varshney , I have read your query in detail , I understand your concern.
Reading out your case scenario, following are the possibilities in my mind:
1. Allergic cough with post nasal drip.
2. Acid reflux associated with Laryngo esophageal Reflux (LER).
Get a Chest Xray done, if there are no sign of infection then, you would be treated for Allergic cough.
Initially you would be treated with a combination of Levocetrizine and Montelukast.
But your doctor will examine your chest for any wheezes/spasm.
In such scenario, your doctor would prescribe you inhalers.
For acid reflux associated with LER, you should take a combination of Pantoprazole and Levosulpride. Walk after all you meals and specially after dinner. Make sure you don't eat heavy dinner.
This is my personal opinion based on details available here. If you still have any other query, you may please ask me.
Stay Healthy.
