Depends: Epidural injections can be done with a variety of medications, including steroids and/or local anesthetic. Some people have instant benefit, whereas others develop an improvement over some time (potentially up to 2 weeks before getting relief). Part of this is due to the medication "cocktail" used and the pathology of the area.

Immediate to never: There can be a wide variation on the response to this injection & symptom relief. First, it works best for radicular pain & when the needle is guided under fluoroscopy as there can be up to a 30% miss rate if not done that way. For some, there is immediate relief while for others it may take a few days if at all & may even require a series of 3 injections. Overall, there is about a 50% success.

Steroid injection: It usually takes a few days for the steroid to be effective. There is a wide variation on the response to this injection & symptom relief. The duration of relief also varies.

A few days: up to 2 weeks in some people. If you haven't had even a little relief after 2 weeks, likely a different treatment may be needed. If you got some relief, a second epidural can be even more helpful.

3-14 days: If no effect after 14 days then discuss other options with your doctor.
