Thank you for staying online,
I am sorry to hear about your problem, and I can understand how uncomfortable you may be feeling, but hopefully, we can resolve this.
The symptoms you have described of having abdominal pain and other symptoms can most likely be due to gastritis. It is an inflammation or irritation of the lining of the stomach. It is caused by various causes like stress, social habits, chemicals, and infections, excessive use of Nonsteroidal anti-inflammatory drugs(NSAIDs).
To get relief from this, the following treatment measures are recommended for you now:
-Avoid smoking & alcohol consumption (if you do so)
-Don't take fried, spicy, salty, chilly food items.
-Drink plenty of water & keep yourself hydrated
-Avoid late meals
– Lying down with a full stomach can make reflux worse. Try to plan meals for at least 2 to 3 hours before bedtime.
-You can take cap omeprazole (Prilosec) 20 mg empty stomach once a day.
-You can also take Pepto-Bismol 2tsf thrice a day after meals.
Both of these medications are available over the counter (OTC) without a prescription & should help you greatly.
I hope I have been able to clarify the situation for you and helped in resolving your query.
I am available to answer any follow-up questions that you may have, so please feel free to ask.
