Hello!
Hi, If I were your treating Doctor for this case I would probatory subscribe an antibiotics for example (
cephalosporin) and see you again in 1-1,5 months and have a control
ultra sound of the neck
lymph nodes. Its very important to describe the architecture of the nodes (regular? homogenous etc) If the size was the same or bigger the next step I would do were a serology inclusive ( EBV, CMV, Toxoplasmose and Bartonella Henselae )
In your case you have a positive EBV. An IgM Antibody proofs a fresh infection while a negative IgM and positive IgG Antibody most probably excludes a fresh infection.
Having enlarged lymph nodes over a year and losing appetite should be further checked. In this case you should find an Otorhinolaryngologist to check your throat up to
larynx and a
biopsy of your biggest lymph nodes should be taken. There are 2 possibilities of biopsy.
1) needle biopsy in
local anesthesia. Its minimal invasive and just local anesthesia but the microscopic examination is difficult
2) Total lymph node extraction in total anesthesia including a panendoscopy. If you smoke you should take the second option.
After the pathological examination let me know the results.
I wish you good health.
