Patient: Examination and laboratory tests: The lump started to appear around December 2012 and then collapsed on itself, and has been hanging 3 bottles of saline during that time. Treatment: I was only diagnosed with perianal abscess, and because I was 9 months pregnant at the time, the doctor said to wait until I had the baby before operating, but now I am bleeding in the stool just after I got out of the month History: I have never had an anal disease before, and I was suddenly diagnosed with perianal abscess in December. It had broken and now it has grown back, but it may still be producing pus. It is very close to the anus. The bowel movements are once every 3 days, a little constipation. Recently, I had bleeding in my bowel movement, bright red blood, the amount is average. Or is it something else? The actual fact is that you need to come to the hospital for a checkup to be clear.
