Usually patients are pain free or with minimal pain at six months post cervical fusion. If the patient still has some pain, they should consult their spine surgeon. Occasionally there may be nonunion, that means the bones are not able to fuse, which may be causing the residual pain. Certain investigations like X-rays or maybe CT scan may be needed to confirm the finding. Rarely, the patient may have infection that may cause some of the symptoms and need to be investigated and treated.
