Sorry to see about your dad, Bazza. As for your own situation, do you think this is the final stage or the start of the final stage? The mesentery is a web-like structure that holds everthing in place in your abdomen. What pain relief are you getting?
Remember what Spurspark used to say, "it ain't over till the fat lady sings" so I hope that la grosse dame is still in rehearsals and not planning on singing just yet.
