Contact Dr Glenn Alexander or Dr Pardi, both in the Gastrentetology Dept at Mayo Clinic, Rochester, MN. The contact info can be googled. You need to write a letter describing your symptoms, the tests you have had and results. Ask for an appointment. You will be contacted with a date and time. They do not want any records or images sent to them, you bring them with you for downloading at that station. You will receive a schedule with bloodwork first. They will tell you to plan for a 10 day stay for tests and any exploratory surgery, etc. I suffered with MP for many years. During exploratory I was diagnosed with Carcinoid Cancer which surprised everyone. Good luck. It was the best decision I could have made. I am a Stage IIIB rare cancer survivor. They saved my life.
