Hi....recently noticed uneven collar bone & my right shoulder is lower than my left shoulder. No pain to the touch. None. Neck xray two years ago ( limited range of motion and stiffness) shows some degenerative disc stuff, maybe some arthritis, but have had no treatment. I continue to do 2-3 yoga sessions/wk and get to the gym 4-5 mornings each week. It was my son who noticed the protruding collar bone. Not sure if I should go to my GP, a chiropractor or orthopaedic dr....Thanks...
