[|Human|] I have just noticed a hard like painful, marble sized lump at the base of my neck on left side at the top of my spine. My neck is very stiff and feels like a muscle pulling down into my shoulder. The lump moves when I touch it, and feels like a marble. What could this be? Any idea?
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. You may have occipital lymph node enlargement. Or you may have some soft tissue tumor like lipoma or neurofibroma. You should go for fine needle aspiration cytology or biopsy. It will give you exact diagnosis then you should take treatment accordingly.
