Hello. Very Good evening.  I'm Dr.Yogesh Kr Sharma. By reading you history,  I think you are wrongly advised and treated. I understand that Ultrasound Whole abdomen is necessary,  but if the report is normal, then why to do repeatedly Ultrasound unnecessarily. Yes I do agree you might be suffering from Chronic Gastritis or Acid peptic Disorder or simply saying stomach Ulcer. I advice you to undergo upper gastro-intestinal endoscopy for the accurate diagnosis, which not a Single doctor has advised.  Upper gastro-intestinal endoscopy is the corner stone for making diagnosis.  I advice you to seek a good gastroenterologist in your area and may be upper gastro-intestinal endoscopy is not required. Please take it seriously,  you are so young and have a upset upper gastro-intestinal tract. This is the only way, you can get rid of this ailment. I'm so much worried about you,  wish you were in contact with me. Regards. Take care and have a hasty recovery. Bye.
