<s>[INST] The right side of my chest bone (below the neck and over the breast) sticks out more than the left side. It s not a bump really but more like a hard bony swelling, not very prominent unless you run your hand over it. I got an ultrasound done and there were no lumps or mass detected. [/INST] Hi Thanks for your query have gone through your query and understand your concern. This is not a disease. One side of ribs are prominent more than other side. There is nothing abnormal, it is seen in many normal people. No treatment is needed however to allay your anxiety you can consult an Orthopedic. You can discuss with your doctor about it. Hope your query get answered. Wishing you a good health. Take care. </s>
