When I'm in bed ready to go to sleep I suffer from chest pain and tightening sensations in my left arm.I've had two admissions into hospital as the pain has been that bad in my chest, three ecgs and various blood tests. My dr said its not classic symptoms of someone with a bad heart. I'm under a cardiac nurse who is sending me for a traed mill test as she said it could be angina, but that pain would normally happen after exhaustion and as mine is'nt she cant be sure. I'm due to fly to Turkey on the 14 of this month and need some advise on how to keep save while flying. can anyone help please coz I'm really nervous about being on the plane.
