The medical term for the condition commonly referred to as " humpback neck " cervical kyphosis or cervical lordosis, is caused by an abnormal curvature of the cervical spine (neck area). Among the reasons for this are congenital abnormalities, degenerative changes in the spine, trauma, and poor posture. Symptoms may include stiffness, tingling in the hands or arms, headaches, and neck pain. Treatment options include physical therapy, posture correction, and, in severe cases, surgery. A humpback neck can only be effectively treated with an early diagnosis and the right therapy.
