I had a slipped C-6-7 and bulging discs between C3-5. I had to clean out my liver that has something to do with the cervical discs, then the manual, chiro adjustments to the atlas/axis I have now are doing some good. The activator didn't do anything for me even with most of my liver cleaned out. Maybe I didn't say this right, but all the chiro adjustments I am having now are really working. One person's opinion.
