Hi my daughter is 3 years old and about 9 months ago I noticed a little lump on her right side rib cage which was really hard to touch but some days it would stick out more then others and when she's relaxing I can feel something moving a little bit, I was so worried obviously so I made a doctors appointment they had a feel and told me not to worry so much it's just the way her rib cage because she has (pectus excavatum) which means her chest goes inward's, I have been 5 times to be told the same thing I just can't seem to stop worrying about it but I feel like am getting no where with the doctor's. I just want to know if anyone as been threw the same with their little one advice would be amazing please,
