Hello Doctor. I have a problem of irregularity in bowel movement and a feeling of incomplete evacuation near anus after bowel movement (problem is nearly 3 years old).I need to go for bowel movement 2 to 3 times a day. And I feel incomplete evacuation (like itching, irritation) neat anus after bowel movement. And so I again have to go for emptying bowels after 2-3 hrs or more. I have taken many laxatives, fibre etc. These drugs help me somewhat but doesn't cure completely. And I have to take fiber (isabgol) daily for helping me a bit. irritation or itching at anus increases when i start to walk and decreases when I sit down or stand still.I also had "left side colonoscopy" done, but doctors say report is normal. My age is 20 yrs, Ht : 5'7 , Wt : 63 kg. PLEASE HELP ME TO CURE MY PROBLEM.
