Potentially: A Medrol (methylprednisolone) dose pack is basically a regimen of oral steroids, usually taken for anywhere from a 6-15 day course. Steroids are very potent anti-inflammatories and so can help inflammatory conditions such as a radiculopathy secondary to a herniated disc. The effectiveness, and also the time they last vary tremendously. Steroids can cause multiple, severe side effects but usually more in chronic use.

See detail: A Medrol (methylprednisolone) dosepack carries little risk unless you are diabetic. It can help low back issues and is worth a try. More often its benefit is short term. Targeted injections may have greater benefit.
