aren't useful or needed. But if your medical history and physical exam suggest
a more serious condition (such as a tumor, infection, fracture, or severe nerve
damage), or if your leg pain and other symptoms don't get better after 4 weeks
of nonsurgical treatment, your doctor may order X-rays.
Other tests, such as blood tests, may be done to rule
out other conditions.
The following tests aren't used as often as an MRI
or a CT scan, but they may give your doctor more information:
A myelogram may be done if you can't have
an MRI (for example, if you have a pacemaker) or if the results of an MRI
Discography can help diagnose disc
problems but is rarely used.
A nerve block may show which nerve is
causing a problem.
