Last year I had viral bronchitis that was treated with antibiotics. Treatment did not work and they put me on prednisone and "mis"-diagnosed me as COPD.
Long story-short... I ended up with congestive heart failure and a pulmonary embolism. My heart was only pumping at 19%. Cardio doc did a swan catheter surgery to drain the fluid off my lungs and I felt so much better.
I now take Entresto and Metatoporol (BP medicine). I tried to wean myself off the meds, but I'm afraid the damage is permanent.
Oh well... I feel great now!
