Upper Back or Arm Pain | The Gilbert Clinic
Because your neck is responsible for constantly supporting and moving your head (which can be about 14-16 pounds), it often can get injured.
The spinal nerves in the neck (brachial plexus) send nerve impulses to areas of the upper body. These large bundle of nerves run down your arms and upper back. In some cases, if your arm is hurting, it could be directly correlated to a problem in the neck.
Some common symptoms in the arms are numbness, tingling, coldness, and pain. Most common neck and upper back pain is caused by poor posture, stress, disc problems, and pinched nerves.
Chiropractic care: massage therapy, ultrasound therapy, ice therapy and specific manipulation can relieve the symptoms associated with this condition.
