I have been having abdominal pain surrounding the Belly Area for 4 months . Initially I have shown it to General Practitioners , He prescribed PPI, Drotin m ,Buscopan for the next 10 days . Got Relief for 1 month and then again it started. I noticed that whenever I eat oily food from outside. It started . I have shown it to the consultant Physician . He prescribed Cizaspa x Tab for 1 month with Gastric Syrup. But Pain was like only constant. Finally I Decided to go Gastroenterologist. He did Few Test like CBC , kft ,Lft ,CRP which all came Normal. Next Step he Did Endoscopy where he Diagnosed H pylori infection. He was given 15 days of course of Double Antibiotics with PPI. Almost 11 days Over but why Pain is not decreasing. Can Any expert suggest ,why it is ???
