Constant stress: This can be caused by poor posture, sleeping positions or repetitive motions that put persistent pressure on the same nerve. Your head may only weigh 10-12 pounds, but looking down at a screen can put up to 60 pounds of pressure on your neck.
Sports: Extreme exercises can squeeze a nerve and cause it unfamiliar stress.
Bone Spurs or Growths: Bone spurs are small, pointed outgrowths from bones. These growths can occur due to osteoarthritis or tendonitis.
Narrowing Spinal Space or Degeneration of Spinal Discs: A condition called spinal stenosis can cause narrowing of space between your vertebrae, which can put pressure on your neck. Age and other factors can cause the discs between those vertebrae to break down and squeeze your nerves.
