Hi Nicole! 

Sounds like a pretty complex case. 

What were her symptoms of MS prior to the onset of GBS? Was she already week in her hands and feet prior? 

This population is definitely not in my area of expertise. However, I do know that in demyelinating conditions, especially progressive ones, you can make a person regress by introducing too much stress to their system.  If you were to needle this patient, I'd recommend getting physical consent first. 

If the physician agreed to my treatment plan, I would opt for a conservative dosage.  Primarily superficial needling of the homeostatic points in the involved extremities avoiding any areas of sensory denervation and progress to basic deep needling w/o manipulation as needed. 

I found a case study where a person with GBS was treated with acupuncture and they had positive results. Here is the link to that.

Keep me updated on how your patient is doing!
