What's the difference between painless delivery and epidural or spinal?

Technique. Labor inevitably causes discomfort or pain from uterine contractions. To have a pain-free delivery, you would need medication. Some women choose IV pain medications. Others chsose epidural analgesia, which involves numbing medication (local anesthesia) injected into the back. Spinal also involves numbing medication, but is used more for surgery or c-section than for labor.
