Suggest Treatment For Swollen Lymph Nodes And Fungal Infection On The Neck

Hello , I have had swollen lymph nodes for a year now almost , they started out in the start of June and I had a pain in one side of the throat . The doctor ordered for an Ultrasound and the results were cervical lymphodenapathy And swelling of 5mm and 4mm . I have had no symptoms whatsoever , however I have lost some amount of weight during exams times and I had acid reflux problem and I think i lost weight because of that . The problem here is that a few days ago I found a small lymph node in my collarbone . It s really small almost insignificant and you really have to dig in to feel it . I had gone to another doctor who also dismissed my concerns. Also I forgot to add that I had a fungal infection on my neck a month after these nodes started to pop up . I want to press for a biopsy but my mom says that I m completely okay and i shouldn t do anything . I m 16 and i weigh 119 pounds .
