Round lump at tip of shoulder blade after shoulder injury. is that scar tissue? no pain when touched. will it cause problem? see what type of doctor?

Shoulder: Depending on what part of the shoulder blade it is located on it could be some calcification that has developed after the contusion that occurred, probably the best person to see would be a orthopedic surgeon who could further evaluate this concern, they could possibly get x-rays if indicated or obtain an MRI to make sure this is nothing more then post from attic scar tissueor calcification. Good luck
