Can severe ibs cause shooting chest pains and lower back pain? i was diagnosed with severe ibs today and i have really bad constipation.

IBS signs/symptoms: The GI tract has a very limited # of symptoms to signal its distress--nausea/vomiting, diarrhea/constipation, bloating, pain, fullness, bleeding, etc. As you know, many of these characterize ibs, but are also seen with inflammatory, infectious, ischemic, malabsorptive, and functional disorders. Directed lab work, imaging, biopsies, stool studies are appropriate in excluding non-ibs pathology.
