[|Human|] Have a hard immoveable lump more like a hard spot on the left side of my neck above collar bone. almost feels like it is on the main core muscle of the neck. 25yr old feamle 125lbs feel healthy other than stiff neck about three weeks ago when first notice the hard spot. What do you think it could be?
[|AI|]  HI. Thanks for your query. Hard immobile lump is to be worried about. I would suggest you to go for FNAC- fine needle aspiration cytology to start with. CT scan of the area if there is suspicion about secondaries (of cancer). A good clinical evaluation by a Surgeon to feel and examine the Chat Doctor. X-ray of the chest, Mammography if you are a female patient. All this is required to determine the future course of management. FNAC can guide further, if not conclusive to go for biopsy to get an accurate diagnosis and plan for further management.
