Spinal curvature is a condition in which the spine is abnormally curved. It is divided into two types: kyphosis and lordosis. Kyphosis is an excessive outward curvature of the spine, while lordosis is an excessive inward curvature of the spine. Both conditions can cause pain and discomfort, as well as difficulty with posture and movement. Treatment for spinal curvature depends on the severity of the condition and may include physical therapy, medications, or surgery.
