Conversation: The conversation between human and AI assistant.
[|Human|] My 12 year old son just found a small lump on the right side of his neck. Dependent upon how it is touched it hurts a little. We didn t realize it this morning when he had his physical exam. Should I be concerned? If he lifts his neck up the lump is visible.
[|AI|]  Hi.based from your description, it could be a possible cervical lymphadenopathy (inflamed lymph node) probably secondary to a recent upper respiratory tract infection; a possible lesion of thyroid or salivary gland in origin. Thyroglossal duct cyst and other considerations like fibrous, lipoma or cystic formation must also be ruled-out. It is best if you consult with a doctor for physical examination and clinical evaluation. Diagnostic examinations such as neck ultrasound, ct-scan or x-ray, thyroid function tests and tissue biopsy may be recommended as needed.  Subsequent management (medical and/or surgical if indications are found) will be directed accordingly. Hope this helps. Good day!!~ Chat Doctor.
