do you know most of the Back Pain Problem is confined within Disc structure like disc material, Nerve Entrapment, Canal Stenosis.may present with low back pain radiating down to leg, with paresthesia, numbness, tingling sensation etc
for that most of time people start treatment pain killers and bed rest.unless not required such type treatment do not offer much benefit.
very strange how a doctor see your details study in X-rays, where one can see only bony structures.how the nerve or disc and other soft structure visible.unless not evident by MRI study.short term medication can be think, but if you had chronic problem extend beyond few weeks to month, should be supported with MRI atlas.
