Yesterday i had this sort of pain but it continues to the centre of my abdomen. On july im going to have an abdomen ultrasound. What can be the causes of this pain pls. Thanks [/INST] Hi, Thanks for posting your query. Do you have fever/ spasmodic abdominal pain/ vomiting? Do you have acidic belching/ abdominal heaviness/ constipation/ diarrhea/ excessive flatulence/ yellow discoloration of eyes and urine? What are the aggravating and relieving factor for abdominal pain? With the available described symptoms, there could be possibility of gastritis, cholecystitis and pancreatitis. You should consult with internal medicine specialist/ gastroenterologist and should go for thorough check up. You should go for complete blood count, erythrocyte sedimentation rate, ultrasound imaging, and serum electrolytes, renal function test, liver function test and serum amylase. Meanwhile, you should take proton pump inhibitors along with prokinetics. Take soft diet along with yogurt and banana. Take care,  </s>
