There are many possibilities about what is causing recurrent pericarditis, but I suspect that a connective tissue disorder like lupus is the underlying cause. However, I urge you to get prompt medical attention for the bleeding you have noticed during bowel movements. Washington University in St. Louis is an excellent medical center and I'm sure you could have your evaluation there. Dr. Paul Robolio is an excellent cardiologist at Washington University who I would recommend if you chose to go there. I hope you find this information useful.
