Military neck, also known as cervical kyphosis, is an informal name for cervical spine deformities that cause unusual curves in your spine. It is not connected with the military. Normally, your neck has a slight backward C bend, but if you have military neck, your neck has lost some of its normal curvature, making it abnormally straight, which can cause your head to tilt forward. Both children and adults can get cervical kyphosis, and there are several causes for this condition, including degenerative disc disease, poor posture, bodily trauma, and certain medical conditions such as osteoporosis, cancer, muscular dystrophy, neurofibromatosis, and Paget’s disease. The most common symptom of military neck is pain, and as the curve worsens, it can cause trouble swallowing, trouble breathing, back pain, spinal cord compression, head bending forward, trouble lifting your head or moving your neck, vision problems, muscle spasms in your back and neck, headaches, and in severe cases, your chin might eventually rest on your chest. Treatment options for military neck include physical therapy, lifestyle changes, and surgery when necessary.
