A client’s sister has had thyroid problems since she was little. What is the cause, and what can be done to help her?

This is a consequence of a long-standing chronic viral infection she had when she was young. The Lightworker Healing Protocol is the best answer here as it addresses all manner of physical maladies and the interplay of karmic forces—that and prayer work are the answer for her. As is usually the case with long-standing problems in people lacking a true awareness of these phenomena and the workings of the divine, her belief in her condition will be an obstacle to healing. That cannot be helped as we cannot override her beliefs, but this can be worked on behind the scenes. It will take a long time but it is doable.
