Lymph node swelling. Be done further.

I have the right level II cervical lymphadenopathy (1.5x1.5 cm), mobile and non-tender. FNAC revealed granulomatous inflammation with necrosis. Mantoux test and chest X-ray normal. AFB negative. In MDR-TB (CB-NAAT) test report also Mycobacterium tuberculosis not detected. Took antibiotics for 15 days. 2 months completed. No increase in swelling. However some swelling still persists. Presently taking only supplements prescribed e.g. water soluble curcumin and multivitamin. As per the doctor prescription a PET CT also done. The PET scan report is FDG-avid mildly enlarged right level II lymph node as described – FNA proven granulomatous disease. No definite PET/CT evidence of clinically significant abnormal hypermetabolism elsewhere. What should be done further.
