Doctor I have problems when I passing stool. It's been so many years that problem started. 3 years before I done colonoscopy but nothing is founded. But still now also I have problems. I felt difficulties in passing stool. Sometimes I feels like burning in my anus and sometimes blood is coming when I passing the stool. When I passing the stool I saw the blood drops. And also I feels pain in my duct. And sometimes when I look into the outer edge of anus, there is blood wounds. And also in morning when I go to toilet I felt that my waste is not completely discrete. I felt like waste is still in my stomach. And after sometime I have to again go to toilet and that time also remaining waste is going. I don't know what's the problem that disturbs me. Is it piles or is it ulcer or is it colonel cancer. I want to be free from this. What all checkups I have to do. What food I have to eat. For more than 2 years I haven't take any medicines.
