Atlas chiro and other upper cervical chiro treatments take time. C-1 and C-2 don't just pop back into place like the lower vertebra do. You should ice after each treatment to reduce the inflammation cause by the treatment. You also need to be very disciplined to maintain good head and neck posture when resting and sleeping. You can work against his effort by being sloppy with head and neck posture.

Regarding chiros messing up people. Chiros pay far less in malpractice insurance than M.D.'s because the risk of bad outcomes is so low.

You are fortunate your insurance is covering Atlas chiro. Most insurance will only cover the adjustments, not the x-rays or other diagnostics. Personally, I am confused how a chiro can plan your treatment. Every body and injury responds differently.

I hope you gety good results.

My best to you.
