Husband took our daughter to her doctor appointment and her doctor said she has a slight heart murmur but it's normal. A heart murmur is not normal. I absolutely hate this doctor. I just called and put in a request to change her doctor because there's a list of reasons why I dislike her. But this last visit of her telling my husband not to worry about a heart murmur is not okay. My daughter will no longer be seeing her. Once the change has gone through I am making her an appointment to be seen and figure out what this heart murmur is all about.
