I was diagnosed with IBS about 7 years ago. I have a combination. The past month or so I have noticed mucus in my stool. I've noticed it in the past every now and then but its been allot lately. Not everyday, but 4 or 5 days out of the week. It is usually clear or yellow. I haven't noticed any blood in a long time. I do have some pain off an on...its in my left lower abdomen. Any ideas?
