My husband had lung cancer 5 years ago and so far looks clear! Radiation challenged his right lower lobe and the pleural cavity gets some fluid in it! Several weeks ago, he had a thorensentis , dr hit a vein cavity filled with blood! After 12 days in hospital he came home with 2 tubes in his right chest cavity, one became infected, causing dr to pull them! Now 1 day after this he feels horrible, having so much shortness of breath, dr sent him for an ex ray , fluid showed better than when he went in ! Now his ankles are swelling!!! They have done so many tests on his heart, and other than his vegal nerve being sensitive, have found nothing wrong! One dr said something about a pacemaker! He is taking Diovan/160mg 2 times a day. Metoprolol 25mg/ half once a day, was prescribed Amlodipine / 5 mg 2 times a day but makes him feel even weaker! His blood pressure in the hospital no one one was concerned with! Right now he runs around 122/66 pulse 104,do you have any ideas?
