I did 40 sessions at the first of the year. It completely reversed a spread of CRPS to my left foot that was starting exactly the same as the right foot. It made me less dizzy and clearer headed. It did a lot of good for me in other areas like joint pain. It helped my migraines. It did not do much for pain or swelling in the original affected areas. I was pretty surprised it didn't really help the swelling in my right lower quadrant. It significantly decreased the burning pain I was having in areas that were not originally affected. I think it's helped some people more than others. But no bad side effects at all.
