Thanks for your query.
Cervical problem is usually seen in school children and is associated with wrong posture while studying.
shoulder knots could be tender points,relax it is not scoliosis
which is a congenital defect in spine,
I advise you not to get her massaged ,inappropriate technique leads to more damage,
You should consult orthopedic surgeon for its proper evaluation,she needs a session with physiotherapist who will advise correct posture and proper exercises.
Wishing your daughter good health.
