Is my client truly infected with parasites, as she believes? If so, what is the reason, and will a session with the Lightworker Healing Protocol clear it completely?

This is an interesting case study for you from several standpoints. She does have Morgellons, for example. She also has an unusual tropical parasite, and that is what she observed directly in her bite she received in Jamaica, followed by unusual lesions breaking open and seeing what looked like eggs and strings coming from the wound. In addition, she has vulnerability karmically to such infestations and this is allowing her to be vulnerable to additional sources of aggravation. So, in a sense, she is a perfect habitat for such organisms because of it. Her karmic predisposition is not due to something more profound, like a history in the Mercenary Army Program, for example, so this is not retribution from the Extraterrestrial Alliance, it is simply that she is a vulnerable human and particularly so because of her past karmic history, and that is why she has this chronic problem. The Lightworker Healing Protocol is a perfect first step to use for her, and then see how things go. There may be further work that can be done for the karma involved here via subconscious channeling down the line if the symptoms do not recede.
