Hello,
Welcome to icliniq.com.
I have read your query, and I can understand your concern. Lymphadenopathy is benign and self-limited in most patients. It refers to lymph nodes that are greater in size than 1 cm or abnormal inconsistency. A detailed and relevant medical history and physical examination are needed to find the etiology of the lymph node enlargement.
In the USG report done four months back, it was present only on the left side of the neck, and now the report of this month says it is bilateral that is present on both sides of the neck. The report in itself does not give any clue towards etiology except it suggests prominent lymph nodes. You also mentioned taking an antibiotic course after the first test. I would like to know the answers to the following questions:
1) Does lymph node swelling or your symptoms get resolved after taking antibiotics?
2) Did you have any recent fever or chills or sore throat, or viral infection?
3) Have you experienced any weight loss?
4) Do you have any constitutional symptoms like fever or night sweats or malaise, or fatigue?
5) Do you have any autoimmune symptoms like arthralgia, rash, joint stiffness?
Physical examination, including lymph node quality like warmth, tenderness, mobility, consistency, has to be assessed, which gives a clue to the possible etiology of the enlarged lymph node. You should visit your doctor. Doing a physical examination along with medical history might give her a hint. She may prescribe another course of antibiotics if it is related to infection, or you may need to undergo CT (computed tomography) scan along with a blood test. If needed, FNAC (fine needle aspiration cytology) can also be done to rule out the cause.
Would you please reply to the above questions to find a better solution?
I hope you find my reply helpful. Thanks.
