Hello everyone I've joined to ask others experiences. I have a 17 month old little boy, this weekend I have discovered a pea sized hard moveable lump just underneath the collarbone just to his left. He has just developed a cold however is well and doesn't have a sore throat or swollen neck glands. He is under consultant care due to a chromosome disorder and has recently been dropping weight. I absolutely will be seeking a professional view tomorrow however just wondering if anyone has any similar experiences or what I can expect? Thanks for reading guys xxx
