Overall neck pain is considered benign, meaning it isn't life-threatening. It is also referred to as self-limiting, suggesting it doesn't usually get worse, even if it doesn't get better.
Pain that lasts more than three months is considered chronic. Sometimes patients have acute flare-ups of their chronic pain. The symptoms get worse suddenly after any number of different triggers for each person.
If you notice the flareups occur less often, are shorter in duration, and recovery time is faster, then you may be seeing a gradual improvement. Many patients do experience full recovery, but no one seems able to predict who will have that response and who won't.
