My mother is 52 years old, she has experienced a growth in her Clavical Bone ends (collar bone, where it meets), the growth is slow and is initiated 3 years back. Intially she didnot had any pain, but from past some time she is expereiencing some pain and though it is not at any joint side but still there is some sensation when she bends downwards.
She never had fracture or any injury. She has a history of Thyroid (bith Hypo and Lupo)
What can it be? Please guide i am very much worried.
