Our shoulders, arms, and hands have sensory nerves that originate in the neck. These nerves exit the spine and pass through openings, called foramen, between the vertebrae on each side, then travel down through the shoulder and upper extremity all the way to the hand.
Numbness, tingling, pain, altered sensation (hypoesthesia, which is a decrease of normal sensation, or hyperesthesia, abnormally heightened or pronounced, sensations) are signs that the nerves originating in the neck are experiencing interference, or impingement.
Impingement of nerves may to due to physical encroachment such as pressure, abrasion, or stretching, and can be caused by abnormal misalignments of cervical vertebrae or by degenerative changes in spinal structures.
When patients present in my office with these problems, an appropriate course of conservative Activator Chiropractic care, including gentle, precise, directional adjustments with the Activator instrument, ergonomic and postural counseling, prescribed stretches and exercises, and sometimes application of gentle traction, is often the solution.
