Hi , I am new here. And have health anxiety about my children. I have 3 boys and 1 girl. 2 of my boys have mild pectus excavatum. My neice was recently diagnosed with marfan syndrome where pectus is a sign. My niece also has the marfan heart issues. However her dad has those same heart signs. Signs are pointing to her dad's side . My sister and her ex husband prob are not going to do the genetic testing. My kids only have the pectin sign really and their fingers are a little bendy. But that's it. I have moments of clarity and know my kids are fine . But i still find myself obsessing about it and worrying.. I hate the feeling!
