Hello Ousaima,
great how you make use of META-questions, META-meanings and what we have learned so far!
I want you to keep these cases in mind and to review them when we worked through all brain and organ levels.
Then you'll be able to use them as case studies for your exam!
As for this week's task, we wanted to focus if we are able to apply the points/phases model to determine where in the process certain symptoms appear.

The pains your sister experienced (throat/((Digestive - Tonsils|tonsils)) pain and itching) do typically come in repair phases, but that doesn't mean that a conflict is completely resolved/dissolved.
The theme includes the brain stem because of her "money chunk" fears, but this is secondary here. The original conflict was that she felt disparaged regarding her sister, which is a social and self-worth issue of the "new brain". Her ((Respiratory - Bronchial Mucosa and Muscle|bronchial mucosa)) seems to have been affected by a "territorial fear" in competition with her sister.  As it had happened months before, she had already adapted to that situation, but it still hurt her inside which aggravated the pain that comes in repair. The ((Digestive - Teeth Overview|teeth)) represent a "bite conflict", which can be about making a big chunk smaller, but also to defend oneself and to take one's right. This may have been caused by the first conflict she had in regard to her sister, or by her trying to "bite herself through the situation". That the nerve seems to be inflamed shows both that it's in repair and that the conflict runs deep, under the surface. 

Even if you reach consciousness of her conflicts and suggest META-meanings that resonate with her, this is only the beginning of her healing! She needs to integrate the learnings and support her tissues to regenerate. For that she wants to reach the feeling of safety and confidence - here her secondary conflict with the dentist money comes in and disturbs the process!
So as you see there are several levels involved, and you did a great job of initiating a change towards completing the healing. Obviously, she felt taken care of and this reduced the swelling because her body doesn't hold on to ((Urinary - Kidneys - Collecting Tubules|more fluid that necessary)) to the process.
Well done!
