Keep going back to your doctor for answers.  I kept going back to my doctor when I had no answers for my abdominal pain and bowel habit change for three and a half months.  My persistance paid off and I was diagnosed with IBS. 

I had show my prblm 4 md dm gaestro doctor in delhi. But nobody diagnouse my prblm

Do you experience constipation or diarrhoea?   Did your doctor take biopsies for h pylori? Was IBS mentioned?  Keep seeing your doctor; they are the only ones who can disgnose you.
