Lymph Nodes
Many children have small lymph nodes in the neck which increase in size with colds and sore throats. They may be tender during the illness but settle back down in size when the child gets better.
Lymph nodes
Single large lymph nodes can occur on the side of the neck in association with recurrent tonsillitis or specific infections.
Lymph glands in the neck always concern parents because of the fear of lymphoma, a tumour of the lymph glands. This presents with rubbery nodes which continue to increase in size and distribution. If they do not respond to antibiotics a biopsy may be occasionally be appropriate. Fortunately most nodes are harmless and reassurance is all that is needed.
