Hi.. Do you have chest pain while taking deep breaths? Any wheezing sound when you breathe? Do you get similar problems earlier?
From your current medication list, I can understand that the doctor has diagnosed acidity problem. Avoid spicy / oily foods, avoid taking heavy meals and take the medications prescribed. Get well soon!
Next Steps
If symptoms persists despite the above measures, consult a Pulmonologist nearby or via online tele-consultation
