Xrays for back pain
X-rays are excellent for seeing bones but don't image the disks well.
Most people with back pain
of less than 6 weeks duration don't require xrays because they will get better with time alone. An MRI
which is very expensive is the test of choice if needed because it can visualize the culprits: pinched nerve
roots and disks with accuracy. It should be reserved for intractable symptoms.
