Thanks for your query.
Enlarged neck glands are very common in children . A pathologic or abnormal lymph
node is commonly quoted to be >1cm in size however in children >2cm is considered abnormal.
Commonly an inflammatory/infectious causes are found.
Pin pointing the exact cause is very challenging for doctors as the list of possible causes is quite exhaustive. If augmentin
fails it is worth considering the option of taking tissue samples by needle biopsy
or excision biopsy.
Have faith in doctors and explore the issue of getting gland biopsy done.
Hope you find the information useful.
