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 cords in the vertebrae send nerve impulses to all areas of the body. These large bundle of nerves will run down your arms and upper back. So unfortunately, 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 achiness. Most common neck and upper back pain is caused by poor posture, stress, disc problems, and chiropractic subluxations. If you are experiencing any of these symptoms or pain, call your Chiropractor to help alleviate the pain!
