Had a abdominal catscan that did not reveal any problems. I have been taking samples of Linzess 291 for about 4 weeks which gives me gas, bloating and partial diarrhea but is manageable. I take Levsin 3 times a day for IBS which takes the edge off. I also take vicodin for degenerative disk disease in spine. I still have the lower left abdominal pain which can radiate up my left side under my rib cage. Looking for anyone in this group that has similar symptoms and if so any suggestions on how to better handle it.
