[|Human|] My son is five years old, he just had a well child check up the doctor said he was perfectly healthy on FRIDAY, it is Saturday around ten and I noticed a small lump on the side of his neck, it moves around it is not puffy. He says it hurts, it appears hard, not red... What is going on
[|AI|]  Thank you for sharing your query on Chat Doctor, I have carefully worked through your case and probably your son have an enlarged lymph node, the function of all lymph nodes is the production of lymphocytes with help defend the body against microorganisms, just try to remember if your son had some problems with his nose, ears, eyes, tonsils, teething or another close inflammatory/Infection diseases. I recommend you monitoring and just in case the lump is getting bigger, painful or swelling a doctor should be consulted. Please kindly rate if my advice has been helpful Wishing you a good health Chat Doctor.
