How long shouls a cervical epidural last?

Anepidural is time released meds and it can last as long as your anesthesiologist sets it to, from a few hours to a few days. I had complications with my C-Section, and they left my epidural in for almost 3 days. That is rare, but it was easier to deliver my meds that way since it was already in place, and the easiest way to relieve my pain after the surgery. They hook you up to a little box that is programed to release little amounts of pain relief at a time. When the box is about to run out of meds, a little alarm sounds, and a nurse will "refill it" with more meds.
