Hello! i am 23 weeks pregnant and for the past several weeks have been experiencing heart palpitations, dizziness, fatigue, shortness of breath, and a constant pain in the center of my chest. My doctor has performed an EKG and an Echocardiogram, both came back normal. What's concerning me the most is this constant pain in the center of my chest. It hurts worse when I breathe in deep and it feels like I am being stabbed with a knife every time I sneeze and it hurts that bad for awhile after the sneeze. Has anyone had this type of chest pain? I just want to feel better and am not sure what I should do in the meantime while waiting for my appointment in two weeks to be fitted for a Holter monitor:( I've had heartburn and this is definitely not heartburn as the pain is excruciating when I sneeze.
