I have notcied over the last year that I have a small lump in the back of my neck on the lefy side, you can feel it real good if I turn my head to the right. Sometimes its sore and gives me almost a sick feeling of I press on it, everyone tells me that its just and infection in my lymp node, but it never goes away. Sometimes its a lot more sore than other times...Has anyone had this problem? I have asked several people and a doctor and the y just right it off as nothing to worry about. Not sure if I should have it looked at again
