Reason of pain during pregnancy
During the labour or delivery there is stretching of the cervix, uterus, vagina and perineum leading to stretching of nerve fibres supplying them, thus causing pain.Epidural anesthesia is an advance in pain management during labour.

Time of anesthesia
It is administered when the patient is in active labour. It can be given as a single injection or in multiple doses through a special epidural catheter by a skilled anesthetist.
It is administered only is advanced stages of labour when cervix opens to about 3-4 cms.
With a local anesthetic, a needle is passed through the space just outside the dural membrane surrounding the spinal cord, spinal nerve, roots and spinal fluid. The patient feels no pain during the whole process except the needle prick.
