Question
Hello doctor,
A few years ago I went to the doctor and had colitis. About 2 years ago, I had a lump in the anus but it didn't hurt. About a few months ago, I was bleeding quite a lot when going to the toilet, sometimes it became a blood stream, but recently it has stopped. But the anal opening is narrow, making it difficult to go to the toilet. The doctor asked me to ask if it is dangerous for people with colitis to have blood in their stools? Due to limited conditions, I could not go to the doctor. Ask your doctor for advice. I thank you doctor.
