hello, I have been experiencing chest pain, shortness of breathe, lightheadedness, innapropriate sinus tachycardia, chills/sweats, palpatations, cold hands and feet(which sometimes turn blue in areas), and when I get up from bed or the couch everything goes black and I feel dizzy it doesn't last long and afterwards I can feel my heart pumping in my head? The other day I went to hospital and they ran some tests the ecg came back OK but a little unusual the chest x-ray came back unusal to. My bp was fine and I had a small tempreture the docter was concerned as I also have an unusual breathing sound on my left lung so he sent me by ambulance to another hospital to get another opinion in the ambulance I still had a small tempreture and a fast heartrate and twice during the trip my blood pressure dropped? They did the same tests at the other hospital and said my heart was fine (good news :]) and sent me home and referred me to a lung specialist I also had pneumonia around 7 months ago what does it sound like is wrong with me? Somebody PLEASE HELP! With kind regards lollylegs_leslie
