I recently saw my doctor because I am having very, very bad headaches. Tests were ran and everything was normal. i was rushed to the hospital this past weekend for the same thing and now they tell me I have an inflamed lymph node on my neck. Should i be worried? i am freaking out because cancer run in my family and how do i know this is not related? I was given anti biotics and were told to take until they are gone. Should I be nervous?
