Adjust the 1st and 2nd ribs. Adjust C1 and C2. Dry needle the scalenes in their entirety and upper cervical spine and send home with a lacrosse ball. The lower the muscle knot along the medial shoulder blade the longer it will take to heal in my clinic. The higher the muscle knot the quicker prognosis.
I would personally take xrays because the cervical spine will show postural issues that need to be corrected if this is not her first time.
