Learn general mobility exercises for neck as well as the whole spine and shoulder girdle exercises.
Learn deep breathing exercises and keep a check on your vital capacity. Balancing exercises, for example, walking with a book on the head with a correct posture, is valuable.
Stretching of the soft tissues and correction of the contractures on the concave side of your spinal curve will form an important part of your treatment.
