Ive had enlarged lymph nodes under my jaw for a year.  Now I have more enlarged lymph nodes above my collarbone on both sides, plus I believe I have a large on under my left armpit.  I frequently run low-grade (100 degrees F), and am very fatigued a lot of the time, with much sleep required.  I did get a FNA on one of the lymph nodes under my neck aroun 8 months ago, and it came back negative.  Should I worry about these additional ones?  Thank you.
Thanks for your query at Chat Doctor. I understand your concern and situation. You are having low grade fever and lymphadenopathy. The FNAC was negative. I suggest you to get your early morning sputum examination for ZN staining and mycobacterial culture to be done for 3 consecutive days. Take an ultrasound guided FNAC and get tested for cytology, ZN staining, PCR for TB and culture for TB to establish diagnosis. Till then eat protein rich and balanced diet with multivitamins and calcium supplements. Yes it is a cause of worry and testing needed. Take care. Best of health
