Thanks for query,
Non specific enlargement of lymph nodes are common.
Most probably it is due to chronic infection in ears,tonsils,teeth,any infection on scalp like dermatitis
In TB,these lymphnodes
If we suspect TB then go for other investigations like blood test
,montouqie test,X ray chest,sputum test.
Otherwise go for general ent check up and go for treatment accordingly.
Ok and bye.
