sophia, have you already addressed all the known nutritional deficiencies seen in ms patients?
many of the nutrients that are low in ms patients are important for vascular health. having low levels is pretty common in places where ms incidence is high. deficiencies can involve sensations of pain.
if you have not seen improvement from the first invasive procedure, perhaps a little bloodwork could be illuminating.
fyi known problems with ms nutrition include vit d3, zinc, magnesium, b12, selenium, vitamin e, uric acid. at a bare minimum the first three would be a great starting point.
vitamin d3 and magnesium deficiencies are particularly known to cause pain (bone and muscle).
if you decide to ask for tests feel free to ask me questions. be aware that in general, poor nutrient levels seen in ms patients still fall within the 'normal range'. please don't believe that normal = healthy. the term normal is a dangerous security blanket term which actually includes a lot of sick people. i can tell you target values seen in healthy controls.
