[|Human|] Hi my son is 7 year old and he has had a bean size movable swollen lymph node on the right side of his neck ever since he was tested positive for mono. My problem is that the lymph node has not gone away, neither has it changed in size. He shows no symptoms of being sick, nor is he losing weight. As a matter of fact he is very active. I took him to a ENT doctor and he basically said it was normal and that my son would be fine. Im just worried this lymph node will not go away and I dont want to wait till it goes down to and later find out its something else.

This may be caused by: A viral illness, such as measles, rubella, chickenpox (varicella), or mumps.  Mononucleosis (Epstein-Barr virus), which results in fever, sore throat, and fatigue, or cytomegalovirus (CMV), a viral infection that causes symptoms similar to those of mononucleosis.  A bacterial illness, such as strep throat (caused by the streptococcus bacterium) or Lyme disease (a bacterial infection spread by certain types of ticks).  Side effects of phenytoin (Dilation), a medicine used to prevent seizures.  Side effects of measles-mumps-rubella (MMR) vaccination.  Cancer, such as leukemia, Hodgkin's disease, and non-Hodgkins lymphoma.  Acquired immunodeficiency syn Chat Doctor.
