What Causes Swelling On Neck Above The Collar Bone?
could be lymph nodes
Welcome to HealthcareMagic.
The swelling could be due to an enlarged lymph node or lipoma or a cyst.
But it will need a clinical examination by a physician as they all have different characteristics like consistently and mobility and plane.
So i would suggest that you show it to a physician once, and get a needle biopsy of it, to help reach a diagnosis.
Hope i have been helpful.
