What is a sprain or strain in the back?A lower back (lumbar) muscle strain occurs when muscle fibers stretch or tear. A lower back sprain occurs when ligaments in the back are torn from their attachments. Because of the function of the back (lifting objects, bending, etc.) it is prone to strains.

Diagnosing lower back sprains or strains
A back sprain or strain can be diagnosed in a full physical exam with your primary care doctor.
Your doctor will take a full medical history and determine how the injury occurred, what the symptoms are and what makes the symptoms worse.
Diagnostic testing is not typically necessary unless the pain has persisted longer than two weeks and is not improving. If pain persists long-term, your provider may order an x-ray or MRI to rule out other possible conditions.
