Hi ! Good evening. I am Dr Shareef answering your query.
One of the common causes of a generalised
lymphadenopathy on the neck region could be a viral fever,
mononucleosis, which are associated with a upper
respiratory tract infection/symptoms.
If the
lymphadenitis was due to simple infection, they would subside with the treatment of the infection. If they stay for longer duration, they have to be investigated upon with routine and some special blood tests, and a biopsy either FNAC or an excision biopsy depending on the position and size of the lymph gland for a histopathology.
In your case, if you did have any treatment till now, I would have prescribed a course of antibiotics for you initially, and if they do not subside, I would go for all the investigations as noted above to arrive at a diagnosis and further management.
Paracetamol might help temporarily for a symptomatic relief only.
I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts.
Thanks for choosing health care magic to clear doubts on your health problems. Wishing you an early recovery. Dr Shareef.
