Does your shoulder or scapula
actually hurt? If not, the reason your scapula is sticking out may be because you have a scoliosis
or sideways curve in your spine which causes a rib hump, due to crowding of ribs and hence the suggestion of removing a rib. I think you should see a spine specialist ( orthopaedic surgeon
who specialises in spine deformity
correction )and take his advice before embarking on any surgical procedure.
