Thank you for this study Ousaima, well done!
As for point 7: "• Pain connected to a relief after accident finished /absence of trigger.
• Pain is stronger when he uses his feet.
• All this indicates repair phase. " 
please put these items under point 5 as they refer to the symptom itself.

Points 13 and 14 don't apply in this case. We only fill these in when we believe a constellation or inner conflicts (an inner tug-of-war) to be present.

META-health practice in this case was to attend to his pain directly, to relieve the energy and to prevent the "((Urinary - Kidneys - Collecting Tubules|KCT syndrome))" (the abandonment conflict that inflates oedema and pain)
