If I were unsure of whether or not is was spinal or something else, I would ask my chiropractor. I see a Network Spinal Analysis chiropractor (and would not see any other, they are very gentle and holistic); you could find one near you at
A few visits to the chiropractor isn't too expensive, and can answer some of those questions. They're usually very in favor of cleansing, as well. Mine got me started on my first cleanse. Good luck!
