IBS problem cause High ESR? Ibs or ibd.

Hi, I have high ESR 32mm and crp is  2 only. I have stomach burning,bloating and indigestion problem also feeling motion sensation sometimes. Even with blend diet,stomach burning is there. Done endoscopy and have mild gastritis. But stomach burning is there very often. Whenever stomach burns, body start to feel the inflammation like internal fever with body burning sensation. After having curd/ butter milk with rice inflammation start to reduce and I am feeling normal. I am urinating more when I feel the body inflammation. Doctor said that it's IBS problem with hypersensitivity gut. I have alternate stool like hard and loose stools. Stomach pain due to gas problem sometimes. Even fruits pomo ,banana causing stomach burn sensation. Kindly give your opinion whether this is IBS or ibd . Thanks and Regards, Ramya
