A small tube of the size of a thread will be passed into the back of the body through an injection. This tube is called as epidural catheter. Then, local anaesthetic drugs, which will numb the nerves and pain sensation, but will not affect the moving ability, will be ministered through this tube. This will provide relief from the pain even though the person can feel contractions. Besides, these drugs will not affect the baby in anyways. However, Epidural is not necessary to deliver, but can have a painless delivery.
