For two weeks I have been short of breath (even talking on the phone makes it hard to breath), had one episode 8 days ago with sudden onset sweating, chest pain, relieved by my dads nitroglycerin pill. Currently having tightness in my veins on both sides of my neck, pain and firmness in upper right abdomen, water retention in face and hands, and having to get up at night and urinate 2-3 times.
