[|Human|] i have a really small lump on back of my neck, left bottom part a little above my hairline. Ive had it for a few days. It feels like a bruise when i touch it and you really have to look for the lump. Other than that no pain at all. What could this be?
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. You may have enlarged posterior cervical lymph node.  It can be due to reactive hyperplasia due to infection.  Or it can be some soft tissue tumor or skin adnexal tumor.  You should go for fine needle aspiration cytology or biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
