Hello I have localized pain on the right side of my neck, very small area, when I press on it. Not sure if it is my lymph node that is painful. What are the possible causes of this type of pain, as I have no obvious infection now, but it all started a few months ago with a severe throat infection, where my glands were swollen and painful. I have a history of breast cancer since 2010 and worried about it. When I went to see the ENT Specialist a few months ago, she said she could not feel any swollen lymph nodes. I think I can feel a very tiny lump that is painful and is most difficult to palpate.
