Dear Sir, A month before I had a PAINFUL swollen lymph node in my right armpit. I had done sonography and Fnac of the lymph node. Fnac showed presence of NO malignant cells and later in time when another sonography was done which showed the size was decreased to half. Test for Tb was done and it was NEGATIVE. Recently I feel the lymph node in my left armpit is causing pain. There is NO loss of appetite. Sonography of abdomen shows NO abnormality. Is this a non- specific infection?
