Practically since the day I became pregnant, I have been having problems with chest pain, shortness of breath, back pain and nausea. Oh, also racing heartbeat (120 bpm) and palpitations (can feel in chest and also when taking pulse). Initially, the shortness of breath was assumed to be my asthma acting up again. But breathing tests assured the pulmonologist that my asthma was not a factor. My OB said shortness of breath during pregnancy is normal. So that alone I could deal with. But I have chest pains and back pains that can be reproduced by pushing, and massage helps. But there is also an internal aspect to it - a deep aching. I'm 18 weeks pregnant, but frequently hit with days of being completely nauseous and unable to keep food down. This has recently progressed to a pain below my breastbone, like I need to burp desperately. I try not eating for an entire day, thinking lack of food will cure that. For three days, I've felt the pain that I can only liken to needing to burp or indigestion. Zantac, Tums and Gas-X all provide no relief. The cardiologist did an Echo, and said I have a mitral valve prolapse with leaflet thickening. I had an EKG that showed a problem with the left ventricle that he said I wouldn't have to worry about for years - not sure what it was. I did not have a stress test or wear a monitor. My question is could this be cardiac, despite being told that my heart is fine? Right now, the back pain, chest pain, nausea, and weird almost blurriness/lightheadedness are making me wonder if I should be in the ER. But as a 26 year old woman, I'm afraid it will be a waste of money since they may not even consider me at risk enough to do any cardiac tests.
