Routine clicking is normal and can come and go on any person. Especially when changes happen in the body due to muscle and tendon position changes while exercising or workouts. If there is pain along with it then you need to get evaluated for any minor tears in the soft tissues of the shoulder. In your case you should be fine if you take some vitamin d and b12 injections. They help healing of minor injuries which could be your cause.
