What they do: Local anesthetics relieve pain by numbing or reducing sensation in a small area. They ease the pain of delivery, but they don't lessen the pain of contractions.
How they're given: Local anesthetics are generally injected around the pudendal nerves inside the vagina. You'll usually respond in about two to three minutes and the effects of the drug may last one hour.
- You probably won't experience any lingering aftereffects. There are no known negative side effects for your baby.
- Pain relief is limited to specific area and it's relatively short-lived. Also, it doesn't relieve the pain of uterine contractions.
