Since this it is an immune driven inflammatory disease DN will not address the actual disease. 

However, DN could potentially help with secondary issues, such as: muscle guarding from fascial tightness, and pain modulation

I see important precautions:

   Since the inflamed fascia is the primary pathology, no aggressive needling (or any initially) into affected tissue bc it will aggravate  symptoms.

   Patients are often on strong immunosuppressive drugs so consideration needs to be made

    The skin and connective tissue may be fibrotic and less tolerant of needling so this is where the Neurologic approach is so beneficial because we can leverage the neurology of the Tibial nerve, sural, common Fib and saphenous so your thought to needle homeostatic points is correct and the safest and initially best patient tolerated approach.  

Hope that helps
