Thanks for posting your query.
With the available described symptoms, there appears to be possibility of Esophageal ulcers or esophagitis
(food pipe inflammation).
Presence of chest pain
while eating and getting relief after Pantocid suggests the diagnosis.
You should consult with internal medicine specialist / gastroenterologist and should go for thorough check up.
You should go for endoscopy for better clarification.
You should also go for complete blood count
, blood sugar and thyroid profile.
All these defined pathology could be associated with Helicobacter Pylori
Meanwhile, you should continue Pantocid along with prokinetics.
You should avoid tomatoes, citrus fruits and oily spicy food.
