Thank you! I think I need to go ahead with the right heart catheter test in order to rule this in or out in spite of what my primary said. With it being said to be "mild" I would be happy to find out I didn't really have that! (Someone on this forum had that experience!) I think I would have to travel to Mayo in Rochester (3 1/2 hrs) or University Hospitals in Iowa City (2 hrs) to find a specialist according to my googling. I can't get the test for a couple months.
