[|Human|] My 10 month old daughter has a lump in her neck that is about the size of a bb. You can not see it but can feel it floating in the neck area. It does not seem to bother her even when touching it. Is this possibly a cyst or lymph node? Is it possibly something serious to be concerned about?
[|AI|]  Hello! You haven't mentioned where exactly on neck is the swelling & if fever is there or not. If on either side of neck, more likely it is a lymph node. If in center & in front of neck, it can be a congenital hypoglossal cyst. Clinical examination is necessary to know the diagnosis. Anyways, as u said the child is playful & it doesn't cause pain on touching, need not go to ER immediately but should get examined once. Hope this information is useful to you. Thanks. Regards.
