I have used Acupuncture.
1st. When I was first diagnosed, my MS symptoms were mild. I noticed that it did increase energy and focus the results were noticable. I used it on a weekly basis.
I stopped for reasons unrelated. I started again in Feb07 after my MS symptoms became quite severe and throut a less severe flare up.
I noticed a mild improvement in my leg sensation after the first visit.
My double vision improved almost completely after the first visit after the last flare up. I also saw her with a feeling someone was tearing my heart out for no reason and the feeling subsided within a few minutes after she placed the needles. I continue today on a weekly basis.
My Acupunturist was clear that this does not cure MS or affect the disease progression. She could only help with treating the symptoms.
My experience is that it helps for me.
My conclusion is that the worse the symptoms are the more noticable the effects of acupunture. This practice is over 300 years old. Those old chinese guys must be on to something compared to the less than 500 year old Western Medicine experts that lack any real level of humility.
Good luck and I hope this helped answer your question
