I started having a lot of really smelly gas last August along with some constipation which was unusual for me. I had always been very regular in my bowel movements. I was due for a colonoscopy so I had one done in September. Everything was ok. Then, about January, I started having streaks of red blood in my stools, accompanied at times, with mucus-looking stuff. I went back to the doctor who did the colonoscopy and he did a sigmoidoscopy. Found some hemmoroids and banded them and said that was probably the problem. I continued to have the streaks of blood and mucus. I went back and he put me on a diet and told me to take Miralax every day, which I have done. The gas, the mucus, and at time, the blood continues.
