Hi. Recently I done my fistula surgery i.e ksharasutra. Wound got completely healed. After one month my anus becomes itchy, sticking and burning sensation. I felt like my anus hole becomes small. After one week these symptoms gone. Later I am getting some blood in my stool i.e from where I had fistula surgery. Later I went to doctor in my location he just checked without any test and told me there is an small fissure and one pile is there. I asked doctor who did fistula surgery to me about the issue. He told be it may be due to ibs. He told me took rifagut 550 mg and cap providac tablets and use them two weeks. Will see later he told. Before using tablets I didn't feel any bloating sensation, stomach pain, diarrhea, irregular bowel moments, constipation. After using tablets on third day I feel like stomach bloating and stomach pain i.e may be due to gas. But I am getting motions normally. From two days onwards I am not getting blood in stool and fissure is not paining much while popping. This bloating and stomach pain is due to side-effects of rifagut and providac tablets. Or is it due to ibs? What I have to do now.
