Hi Kora, Hi Eve, 
Here Eve I wonder why did you consider it as an old brain theme , it can be an old brain theme if we assumed that periosteum is involved here and we can confirm this by further investigation with the client if she feels attacked or something , this makes it an old brain conflict then . This is what I think , do you agree? 
   I Agree with the questions to be asked this will lead us to lots of things :) 
Thanks for sharing this Eve , it’s so beneficial to share thoughts , it brings a wider vision to all:)
