I'm sorry to hear of all the problems that you are having!! These are not our normal everyday problems that you are dealing with, and I'm not really qualified to answer all your questions. However, I have found a site that may help you to understand what it is that you have re Pulmonary Hypertension. It seems to explain it well. Please keep in touch and let me know how you are doing!!
My best wishes to you, Hugs, Teri
PS Here is another very good site to read!
