hi there, you seem to be suffering from peptic ulcer disease
and your treatment lies in taking a course of antacids along with a very regularised and punctual diet with low fat and spices. You will also need to take a course of antibiotics to take care of H.Pylori infection. Get your stool examined for occult blood and that if positive could indicate ulcer bleed and explains the black tarry stools. Endoscopy
may be repeated. Do visit a gastroenterologist and let him evalute you for athe same. Get your hemoglobin
levels also checked as constant loss of even small quantities of blood can lead to iron deficiency
anemai and you may need iron supplimentation.Take care.
