Readers want a number of days, and the range that exists comes with a condition attached.
How many weeks, and for whom
OrthoInfo (AAOS) reports that approximately 80 to 90% of patients with sciatica get better over time without surgery, typically within several weeks if the underlying cause is a herniated disk. Note the condition: the several-weeks timing is tied to a herniated disk as the cause.
Other causes and slower recoveries
No timeline is given for sciatica from other causes, or for patients who do not get better without surgery. Any date offered for those cases needs a clinician's exam behind it. If your pain has gone past several weeks, that is a question for a clinician, not for a forecast.
Questions to bring with you
Ask what is causing your sciatica, since the timing depends on it. Ask what the plan involves and how long you would be committed to it. For general reading, use the WebMD pain management center, the MedlinePlus sciatica page, the OrthoInfo sciatica page or the American Academy of Pain Medicine.
