Hello dear,
The symptoms as mentioned in your post can be due to:
1.
Acid peptic disease. Sensation of pain after eating or drinking is characteristic of Gastric ulcer.
2. Inflammatory bowel disease
3. Gastroenteritis
Since the symptoms are persisting since 02 weeks, you need to be clinically examined to determine the underlying cause & formulate an appropriate management plan.
Investigations like USG Abdomen, upper GI
endoscopy & stool examination will be helpful for clinching the diagnosis.
Symptomatic relief can be obtained with intake of
Pantoprazole preparations (to be taken 30 min before meals) & anti spasmodics like
Dicyclomine preparations (to be taken after meals)
Also, you need to take soft, plain diet & avoid oily foods.
Wishing you a good health.
Take care.
