Call Mayo and say you want to make an appointment with Dr. X in Endocrinology. They will transfer you to that department, and hopefully, you'll get an appointment. Also, Mayo GI prescribed Swiss Kriss for help with constipation. You can order on Amazon; it's Senakot with herbs. 2 at dinner every night for me, and sometimes I take 2 with breakfast, if I need.

I have had similar experience with a month or so of constipation and stomach cramps. My Dr indulged my inquiry for a CT. However, he also recommended Magnesium Oxide (2 at breakfast and 2 at bedtime). It is helping. I have had a CT and will be getting an MRI next week. The CT required two bottles of barium, not too bad. But, I didn't realize that it makes one sleep the next couple of days! For the MRI, I had to get bloodwork re: kidneys as the contrast affects that. I had an allergic reaction to what they used for echocardiograms, and this abdominal (liver) MRI will use a different one. They advise 5-10 days between the two. Just thought I'd share in case you ever come up with this situation.
