Hi, I have been having mild pain, discomfort in my rectum. I abuse alcohol and am 36 years old. Otherwise in decent health. Feeling of a lump or fullness in my rectum seems to come and go, but has been more persistent over the past few days. I have been taking Metamucil to deal with my loose stool. Tonight, finally had a decent feeling bowel movement, but my stool looked Riley and full of mucous. Help!
