I hope you don't have to wait much longer for your diagnosis, LJZ. I did have a Defecating Proctogram the same day as the pouchoscopy (dual procedure nicknamed the Bo Shen Special), which was two weeks ago. It turns out that my pouch had prolapsed well over a year earlier, yet had been missed by 3 surgeons and 1 GI Specialist in my state. However, the early stages of the prolapse were photographed in a pouchoscopy from 14 months earlier. I'm so thankfuI I finally went to the Cleveland Clinic for a proper diagnosis!
In my case, my sphincter muscle was not damaged by not addressing the prolapse for over a year, as was confirmed by a manometry exam. I don't know if this would apply to your situation, though. I don't have answers to your other questions either, but Scott is right and a diagnosis should come first.
Should you have a mucosal prolapse, I would not recommend waiting as long as I did before taking action. This whole business of physical maneuvering is elusive & painful! Hope the Rx is approved by insurance soon.
