Snoopy, I just asked Barefoot about healing the cervical discs. He said use the Spray 111 on your neck as it's effects are cumulative and it has the BF&C herbs in it. It takes a while for the discs to heal. Cleaning out will do it on it's own, but the BF&C formula contain the nutrients it needs to heal.
Good luck, and I hope you keep cleaning out the toxins so you can heal. It will be a long process, but it works.
