Very Large Glands In 4 Year Old

  Since my daughter was about 1 year old the glands on the back of her neck
  have been large and swollen. My doctor has always said it takes a long
  time for them to go down after an infection and I shouldn't worry. Two
  days ago when I took her to the doctor for a bad cold he felt the back
  of her neck and was very concerned. He sent her for a CBC. He said
  everything was OK and it must have been a virus. These glands have been large
  for a very long time and they never get any smaller. I'm not sure the
  doctor was listening when I told him how long it has been this way. What
  could possibly be causing this? Please help and thanks for this service.

Dear Joy :
Developmentally, lymphatic tissue of the body increase rapidly in mass during infancy and early childhood , reaching adult size at about 6 years of age. It then undergoes involution at about puberty.
The peak mass will be evident between ages 4 and 8 years , probably coinciding with peak exposure to various infectious agents for the first time ( in preschool and early school years ).
Previous or recent involvement of the lymphatic tissue with viral or bacterial organisms may have caused some localized lymph node enlargement , most of which will gradually shrink down to their normal size with time.
