[|Human|] I am 18 years old and I keep worrying about my lymph nodes.  I had a firm pea sized movable lump above my collarbone on both sides for at least a year until I went to my doctor.  She thought it felt like a normal lymph node but said it was in an unusual place so sent me to a surgeon.  The surgeon felt the lump and immediately said it was a sebaceous cyst.  After reading about lymph nodes online I was still paranoid.  I started to feel around my neck for lymph nodes and felt a soft movable lump about 1.5cm in diameter on my right side.  I do have chronic sinus infection and allergies so it might just be from those but I am still worried.  When I went to my doctor she felt my neck and said it felt normal.
[|AI|]  Hi. Thanks for your query and an elucidated history. Once the surgeon has said these to be sebaceous cysts you should not have any doubts. Yet, if you still want to confirm, the best way is to undergo ultrasonography and confirm. IF sebaceous cysts, go for removal as they are small the scars will be small. If they enlarge - the scar will be large. IF lymph nodes-insist for Fine needle aspiration cytology. This will give you the specific diagnosis and a way to treat./ get treated.
