Hi!
I think I had similar findings to the other ladies looked at connective tissue, fascia  and tendons as I think these would be the tissues involved?  Perhaps the joint capsules too, but not sure if this would be cartilage..... It appears that a frozen shoulder usually involves the front side so we are looking at embracing, holding and control? 
It would depend on what side is effected to determine involvement...
To me, i see the main themes expressed with this injury are self devaluation, self doubt , overload - I am not enough, I am not strong enough...  
Could this be a theme of the cerebral medulla new brain  - cartilage, ligament and muscle tissue, but also have old brain cerebellum involvement with the muscle fascia and joint capsules?
