I have a palpable left supraclavicular lymph node that i first noticed 4 days ago. it is around 1cm, moves (squirms) around, and was initially tender?

EVALUATION: A supraclavicular lymphadenopathy needs to be evaluated sooner than later so get this checked out by your physician. Good luck

Reactive lymph node: It is not unusual for a person to have occasional reactive lymph nodes that enlarge in response to infections and inflammation. Nodes in that area can react to throat or pulmonary(lung) problems. It could also be a deep cyst or other type of mass. Not to cause undue concern, but enlarged nodes always need to be evaluated for lymphoma. You definintely should get it checked.
