<s>[INST] Hello doctor, I have a difficulty in passing stools and a clogging where the stool passes from the sigmoid colon to the rectum to execute a bowel movement. I just spent several hours of discomfort feeling constipated and as though I needed a bowel movement, only to pass a stool the size of a pea as I began to sit down. I have a big problem with getting anything to pass from the sigmoid colon to the rectum. [/INST] Hello. I have carefully reviewed your health query and can understand how worried you are about your health. Regards. For more information consult an internal medicine physician online --> </s>
