What causes bone on left side of chest larger than the right?
Patient: The bone on th left side of the chest is comparatively larger than the one on the right side. I have this condition from the childhood but now the left side of the chest has started to ache. It is really discomforting. Need your advise.  Regards  Shakir Doctor: This normally occurs when one has a bend in the spine called scoliosis, or vit deficiency in childhood, like Rickets, you need a thorough assessment , and only then things can be finalized.
