Hi Luke! 

I think it's wise to have a cautious start with needling dosage in an individual with MS.  Don't forget to also utilize your QST assessment to guide your needling dosage. 

I would definitely prioritize you're homeostatic points. This is going to help you address the "system" and target neurogenic inflammation. you should still have a few needles to be able to address symptomatic points after that. As her tolerance increases you can add paravertebral points. 

Another option would be to reduce your needle length if need to to minimize size of lesion if her tolerance is fair.
