If your sciatica is truly from the epidural, I'm assuming that you have some (temporary) nerve damage. In that case, time will probably be the healer although B-vitamins may be worth a try. If there is a muscular component (e.g., the piriformis muscle is impinging the sciatic nerve which I sometimes see in pregnant women), then a skilled massage therapist can help. S/he can also show you some stretches.
