Neck Pain
Discogenic neck pain refers to discomfort or dysfunction originating from the intervertebral discs in the neck, specifically the seven discs between the C2 and T2 vertebrae. These discs have a strong outer layer of fibers and a gel-like inner core made of water, proteins, sugars, and collagen. These structures are normally robust and built to last, however the breakdown of proteins and collagen due to aging can result in less structural support for the neck. This often leads to stiff muscles around the joints that are working overtime to stabilize the spinal column. Sometimes tight neck muscles are the body's way of protecting the joint from further damage.
When the annular fibers are damaged, the disc may bulge or herniate, pressing on nearby nerves. Symptoms may include pain, pins and needles, numbness, or weakness in the hands, shoulders, or upper back. This damage sets off a chemical reaction in the body and the immune system will try to remove the debris by creating inflammation. Early disc damage may not cause symptoms since only the outermost fibers have nerve endings. However, disc issues are common, especially as we age.
Most disc herniations occur at the C5-6 or C6-7 levels in the neck. These issues usually develop gradually due to age-related changes and repetitive stress, such as poor posture, heavy lifting, or excessive smartphone use. Reduced neck curvature can increase the risk of disc problems. Understanding these factors can help in managing and preventing disc-related pain.
Other common neck injuries we see in the office are due to instability or whiplash injuries. We find that instability injuries can lead to headaches, weakness, adjustments that don't hold well, irritability, fatigue. We are successful treating these injuries with targeted strength training for the neck among other rehab exercises.
