Treatment of disalignment of cervical spine?

If no pain no worry: If no symptoms in terms of pain or neurologic symptoms or findings, don't worry unless physician believes that the spine has an instability then you would need surgery. Otherwise, the spine can change its alignment due to degeneration or due to muscular issues or even related to disc herniation or spinal stenosis. If those are causing symptoms you treat them, not how the spine lines up !

See below.: Some patients who have an abnormal curvature to their spine will present with neck pain and arm symptoms including pain, numbness, and weakness. The arm symptoms can be the result of nerve compression. Abnormal alignment may also cause spinal cord compression. I would see a spine specialist to discuss your specific situation and treatment options.
