question: hi. i have a 8 month old baby boy and a few days ago we noticed a large lymphnode under his right arm pit. we went to the docters but they have no idea what it is. we did blood test a scan and a sonar. but they still dont know. It measures 18mm x 12mm in diameter. it does not hurt him when we touch it but today he started getting grumpy. He s eating and dringking. the colour is a blue purlpe colour. Please answer me back on my email address as it will alow me to sent you a foto of the lymphnode. thank you ( YYYY@YYYY ) Soritha klopper
