HI,Dear,Thanks for your query to HCM virtual Clinic.
I studied your query in all the details put forth by you.
I understood your health concerns about the Cause of unrelieved lymph node in posterior of your neck.
Treatment -
I reviewed your case, and in my opinion your doctor has rightly treated you.
Its normal to have
lymphnodes even after 10 days of antibiotic course.
Don't worry for the lymphnodes, as it usually takes 3-6 mths to really reduce from its enlargement to normal size.
If You are still suspicious of it being Cancerous , a
Second Opinion from another ER Ent Surgeon would resolve your worry.
I would advise you to consult ER ENT Surgeon in your case,only if it recurs and increases in size and increases in numbers.
As I don't have any first hand information or the photograph of the lump,its advisable to get checked and treated from your doctor.
Hope this would help you to plan treatment as fast as possible with your doctor.
If you feel satisfied with this reply,don't forget to hit thanks and write excellent review comments,which would improve my rating for new needy visitors to HCM.
Welcome for any further query in this regard to HCM.
Have a good day.
With Regards,
Dr.Savaskar M.N.
