Spinal sprain ( lumbar sprain)
Spinal ( lumbar) sprain refers to shock, damage, or rigor of light muscle or ligament caused by lifting heavy objects, performing rigorous work, or doing excessive exercise or due to traffic accident. It is generally described as " I pulled my back" or " I have simple back pain or simple backache that disappears after a few days of rest". Simple lumbar sprain can be alleviated by bed rest for a few days as hospitals suggest, but a significant number of these cases lead to the development of chronic backache or disease that affects everyday life. Sprain of the wrist ankle can be treated by fixing the affected area with cast but can hardly be done for spinal sprain; hence the difficulty of treatment in most cases. Once a patient begins to experience pain in the sprained area, the corresponding muscle and ligament stiffen from the pain; frequently, continuous micro-rupture exacerbates the pain.
