Whole body Lymphadenopathy. What to do?

I have small lymph nodes enlargement over all over body mostly near easy front and back both ears, both sides of neck under law, both sides of armpit and inguinal region more 1.75 years. I visited many doctor even cmc vellore in hematology department they told me blood work are normal any size are small they can't perform fnac. As my blood report and usg of whole abdomen are normal they said when size is more visible then come here otherwise nothing to worry. They even referred me in surgery infections disease departments. Their opinion almost same like if size size increase then come. Hence I am living in a paradise world not able to understand what to do? My armpit lymph nodes are paining ang lingering all the time. I visited many doc in kolkata but no solution. Kindly suggest me what can i do as I can feel these lymph nodes and pain over certain area like armpit under jaw and in front year. And I also diagnosed with retraction of ear drum.
