The spinal cord travels through a central canal in the cervical vertebrae. Nerve roots extend off of the spinal cord and branch off into specific locations into the arm and hand. These spinal nerves provide signals to our muscles to contract or relax, as well as provide sensory input such as pain, pressure, and temperature. If any type of abnormal pressure is placed on these spinal nerves, then we get an impingement, or “pinched nerve.” Some causes of impingement may be:
