What is back sprain and strain?
Back sprain and strain occurs when tissues in the lumbar spine are over-stretched or torn. This is the most common but less severe cause of back pain. Strain applies to injury of ligaments while sprain applies to muscle injury. Back sprain and strain are called musculoligamentous injuries. Clinically, these injuries are associated with muscle spasms and reduction in lumbar spine mobility. Patients feel acute and chronic pain or soreness in the lower back. The pain is aggravated by most physical activities like standing, bending and walking. Normally these injuries are not accompanied by leg pain.
