I understand your health concern.
Let me tell you first that this is a common symptom in the general population. The causes of it can be Acute Gastritis
, chronic gastritis
, duodenal or peptic ulcers, GERD.
You need to get an upper gastrointestinal endoscopy done to confirm the cause and go further onto the management.
Meanwhile, take bland diet, drink plenty of water, and avoid spicy foods. Take small frequent meals.
You can try over the counter antacids like Digene syrup for some time now. Drugs that are more effective are proton pump
inhibitors like pantoprazole
. These are prescription drugs. Please get them prescribed by your primary care
Get well soon.
