Have had upper left pain and squeezing/ tearing feeling behind and above left breast into armpit..... I get winded with exertion/exercise/said climbing.... I am active and eat healthy .... the pain radiates into my arm and behind shoulder blade into back.... I have intermittent numbness in arms and legs as well......I get palpitations at times as well.... I was diagnosed 3 years ago with a trivial leaky mitral valve ....not sure if palps are from the leaky valve? I do get anxiety at times but I strongly believe this is not due to that ....I had chest X-ray troponin , d dimer, ekg and chest X-ray which were all clear.... also a quick echo to check the pericardium which was clear as well.... It hurts to lay on my side and to bend over .... my heart feels like it is spasming at time or so if feels like my heart.... thanks in advance
