I always find myself back on the internet searching for peace of mind. I have been to the cardiologist in April and multiple ekgs but they found nothing. Just went through miscarriage and have had horrible chest pains but I just had what felt like a terrible muscle spasm in the chest. Go scared my heart is failing and then it sends me in panic mode. I have been told I’m fine why is this happening! It felt like my heart was vibrating or bubbling. Please send help or comforting words
