Many conditions are really not well-understood or even yet well-defined...and/or are in need of a new definition.
It can all get to be quite a complicated, messy picture.
I, too, have mutiple diagnoses and often am not always positive of where to post on some issues/topics.
In time, I think we'll find some of these co-occurring conditions have more in common than anyone had ever thought (originally).
I also agree that some conditions and some meds eventually place the body at further risk for even more complications.
This topic was also just being discussed in the PN forum.
Fortunately, we all have each other to try to help to sort out the things we can do to help ourselves as much as possible!

Hopefully, things will get easier for all in time!
