Thanks for posting your query.
With the available described symptoms there could be high possibility of peptic ulcer disease
Peptic ulcer disease is due to Helicobacter pylori
Gastric ulcer gets irritated after taking food and may cause severe pain.
You should consult with internal medicine specialist/ general surgeon
and should go for thorough check up.
You should also go for complete blood count
, blood sugar, serum electrolytes, and serum amylase.
You should also go for ultrasound imaging and x ray abdomen.
You should also go for endoscopy for better clarification of upper gastrointestinal tract.
You should also take proton pump
inhibitors along with prokinetics.
You should avoid tomatoes, and citrus fruits.
