Hi, Thanks for asking HCM.
You seem to have an ulcer may be peptic.
But to confirm the diagnosis you require to go through
endoscopy.
You get your
stool test done for occult blood, worms , ova and cysts.
Till then you should have small frequent bland diet,and lots of water.
Avoid alcohol, tea, coffee,aerated drinks and spicy food.
Mean while you can take antacid in liquid form SOS which works very fast.
You can also try
Proton pump inhibitors with
calcium carbonate buffer preparations for fast relief.
Avoid
constipation, if it is ther you can use mild laxatives.
After investigation you can see your doctor or you may write HCM.
Good day.
