It would be more helpful if you can inform us more about the characters of this swelling like size, if painful, tender, etc.
Is there any history of scalp infected lesions, Ear, Throat, skin infection in the area drained by these nodes? Or did you notice this swelling following any attack of viral infection.
Did you notice any other swellings in other parts of the body?
Is there any fever.
The swelling you have described that is felt on the upper side of the neck is probably enlarged Lymph nodes as it occurs in a Lymph node region, however this must be confirmed by your physician.
Abnormal Lymph node enlargement commonly results from infection / immune response, cancer.
Following infection Lymph nodes become enlarged, painful and tender. When infections resolve, the lymph nodes become smaller in size but remain palpable and never go to normal size.
Direct clinical examination is essential to exclude other causes like abscess, lymphoma etc.
Keep us updated.
This answer does not substitute for direct medical consultation.
