Conversation: The conversation between human and AI assistant.
[|Human|] My son hit his left trapezoid area/collar bone area on the arm of our couch (the wooden part) this weekend, straight on. He is having a hard time moving the arm and there is a lump in the soft tissue area between his collarbone and his neck that is extremely sore to the touch. I am worried about a few possibilities: a clot, a piece of bone or hopefully a muscle knot. Hopefully I have described it in enough detail to have some peace of mind with some sort of answer. Thank you. Trish
[|AI|]  Hi.it is best if you consult with a doctor, preferably a general or an ENT surgeon, for clinical evaluation. Based from your description, it could be cervical lymphadenopathies which may be secondary to a recent upper respiratory tract infection. Your neck lesion could also be of salivary or thyroid gland in origin. These tumor lesions are best evaluated clinically. Neck ultrasound, ct-scan or a tissue diagnosis through a biopsy may also be recommended. Management (medical and/or surgical) will be directed accordingly. Hope this helps. Good day!!~ Chat Doctor.
