I am new around here and have had IBS a very long time. Had stomach & bowel problems since age 5, now 39. Many antibotics throughout my life. Found out I had severe endometriosis while searching for an answer to stomach/bowel problems. Also led up to a hysterectomy and I am presently taking prescription hormones. Have mainly IBS-C/P with some D. My concern is, where is this paste coming from? Is this a normal IBS symptom?
