Hi.
I've gone through your query. I can understand your 
anxiety. 
Your symptoms might be due to GERD, a 
acid reflux disease or other causes too. I advice you, 
- Lifestyle modification:
1. Avoiding recumbency 2 hours after food.
2. No 
smoking.
3. Diet :  Avoid fatty foods,alcohol, chocolates, garlic, onion, coffee. 
If no response, 
4. Elevate head of bed by 6 inches with blocks.
5. Sleep in left lateral decubitus ( left sided) position.
6. PPI (ormeprazole, 
pantoprazole or 
rabeprazole)
Hope I have answered your query. Let me know if I can assist you further. Get well soon. 
Regards, 
Dr. Yogapriya V, General and family physician.
