You have symptoms of chronic gastritis. I suggest you take some drugs to protect gastric mucosa, such as sucralfate, drugs to inhibit gastric acid secretion, such as omeprazole and domperidone, plus some Baohe pills combined with vitamin B6.

Suggestion:

Eat a light diet, do not eat spicy, alcoholic and irritating foods, and drink more boiled water. I hope my answer is helpful to you.
