Pain relief during labour

7-minute read

Labour is painful, so it’s important to learn about all the ways that you can relieve the pain.

It's also helpful for whoever is going to be with you during your labour to know about the different options, as well as how they can support you. Ask your midwife or doctor to explain what's available so that you can decide what's best for you.

Write down your wishes in your birth plan, but remember that you should keep an open mind. You may find that you want more pain relief than you'd planned, or your doctor or midwife may suggest more effective pain relief to help the delivery. Different ways of relieving the pain are listed below.

Natural pain relief

The following techniques can help you to be more relaxed in labour, which can help you to cope with the pain.

  • Learn about labour — this can make you feel more in control and less frightened about what's going to happen. Talk to your midwife or doctor, ask them questions and go to antenatal classes.
  • Learn how to relax, stay calm and breathe deeply.
  • Keep moving — your position can make a difference, so try kneeling, squatting, lying on your side, walking around or rocking backwards and forwards.
  • Lean forward over a beanbag or sitting back-to-front in a chair with some support pillows to take the pressure off your back and abdomen.
  • Bring a partner, friend or relative to support you during labour, but if you don't have anyone, don't worry — your midwife will give you all the support you need.
  • Ask your partner to massage you (although you may find that you don't want to be touched).
  • Have a warm bath or shower.
  • Place a hot water bottle or hot pack or cold pack on your back or lower abdomen.
  • Use hydrotherapy (being in water) to help you relax and make the contractions seem less painful. Ask if you can have a bath or use a birth pool. The water will be kept at a comfortable temperature but it won't be above 37.5 degrees C, and your temperature will be monitored.

Non-medical pain relief


This stands for transcutaneous electrical nerve stimulation. It can reduce pain by delivering tiny electrical pulses to pads stuck on the back, which stimulates the body to produce endorphins. Some women find TENS helpful during the early stages of labour. Find out how TENS might work for you.

Water injections for back pain

Midwives can use a technique involving sterile water injections in the lower back to reduce back pain. Usually injections are given in four different places in your lower back, just beneath the skin. The injections cause a strong stinging sensation, like a bee sting. The injections can bring up to 2 hours of pain relief to your lower back but you will still feel the contractions. These injections will provide a few hours of pain relief without any side effects for you or the baby.

Medical pain relief

Gas and air (nitrous oxide)

This is a mixture of oxygen and nitrous oxide gas (laughing gas). Gas and air won't remove all the pain but it can help to reduce it and make it more bearable. Many women like it because it's easy to use and they control it themselves. There are no harmful side effects for you or the baby, but it can make you feel light-headed. Some women also find that it makes them feel sick, sleepy or unable to concentrate. If this happens, you can stop using it.


Another form of pain relief is the intramuscular injection (into the muscle of your thigh or buttock) of a drug, such as pethidine or morphine. It takes about 30 minutes to work and the effects last between 2 and 4 hours.

There are some side effects to be aware of:

  • It can make some women feel woozy, sick and forgetful.
  • If it hasn't worn off towards the end of labour, it can make it difficult to push: you might prefer to ask for half a dose initially to see how it works for you.
  • The drugs cross the placenta and can make the baby sleepy. If pethidine or morphine are given too close to the time of delivery, it may affect the baby's breathing. If this happens, an antidote will be given.
  • The drugs can interfere with breastfeeding.

Epidural anaesthesia

An epidural is a special type of local anaesthetic. It numbs the nerves that carry the pain from the birth canal to the brain. For most women, an epidural gives complete pain relief. It can be helpful for women who are having a long or particularly painful labour, or who are becoming distressed.

An anaesthetist is usually the only person who can give an epidural, so it won't be available if you give birth at home and it may not be available in a birth centre. If you think you might want one, check whether anaesthetists are always available at your hospital. The procedure and any side effects will be discussed by the hospital staff and can only proceed with consent.

To have an epidural, you will be given a local anaesthetic in your back, before a very small tube is inserted into the back near the nerves that carry pain from the uterus. Medications are delivered through this tube. Your contractions and the baby's heart will need to be continuously monitored by a machine. This means having a belt around your abdomen and possibly a clip attached to the baby's head.

There are some side effects to be aware of:

  • An epidural may make your legs feel heavy, depending on the type of epidural. You'll be advised by the doctor or midwife when you can get out of bed.
  • Your blood pressure can drop; however, this is rare because the drip in your arm will help you to maintain good blood pressure.
  • Epidurals can prolong the second stage of labour, when you push and your baby is born. If you can no longer feel your contractions, the midwife will have to tell you when to push. This means that instruments such as forceps may be used to help you deliver your baby (instrumental delivery). However, when you have an epidural, your midwife or doctor will wait longer before they use instruments as long as your baby is fine. Sometimes, less anaesthetic is given towards the end so that the effect wears off and you can push the baby out naturally.
  • You may find it difficult to urinate as a result of the epidural. If so, a small tube called a catheter may be put into your bladder to help you.
  • About 1 in 100 women gets a headache after an epidural. If this happens, it can be treated.
  • Your back might be a bit sore for a day or 2 but epidurals don't cause long-term backache.

Some women prefer to avoid the types of pain relief listed on this page, and choose alternative treatments such as acupuncture, aromatherapy, homeopathy, hypnosis, massage and reflexology. However, most of these techniques aren't proven to provide effective pain relief. Therapies such as acupuncture or acupressure should only be practised by qualified practitioners.

If you'd like to use any of these methods, it's important to discuss them with your midwife or doctor and let the hospital know beforehand. Most hospitals don't offer them for pain relief during labour. If you want to try an alternative technique, make sure that the practitioner is properly trained and experienced.
