Hi Ousaima,
the information in the article would need to be considered and confirmed by her. This gives a model to explain how self-devaluation has originally happened, and what a UDIN or fundamental sensation may have been about. I find self-devaluation to often be a secondary theme, because one didn't succeed in something of high importance. But this is something to explore with the client.
We always go with the information we have accessible and check this with the individual person. 
So of course we don't need to know all about fascia or what else might be involved when we do META-Health, it's most important to be curious about the client's pattern of experience, the root causes and their individual triggers.
What we see in her case is that the swelling and pain create an inhibitory response (dorsal vagal) and feeling trapped, this produces further helplessness and self-devaluation. We would like her to find more ease to expand and to move in safe circumstances to break the vicious cycle, wouldn't we? This would even relate to her fascia and muscles...
Tissues aren't completely apart, they work together and influence each other. Having said that, this is already quite advanced META-Health! :-)
