<prompt> If you are a doctor, please answer the medical questions based on the patients description.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.  <response>: 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 andor surgical if indications are found will be directed accordingly. Hope this helps. Good day!! Chat Doctor.
