If a someone has IBS, what over the counter products are helpful for pain? I use probiotics and eat yogurt. I also don t have the type with diarrhea, and not exactly constipation either. I Use to have diarrhea, but don t anymore, just abdominal pain. Sometimes I can t eat much because nothing agrees with me and I have lost a few pounds as well. I sometimes get pressure on the bladder as well. This has been going on for several years.
