What pain relief options are available?
Non-medical
- TENS machine — great in early labour.
- Water (bath, birth pool) — proven to reduce pain perception.
- Massage, position changes, breathing.
- Hypnobirthing.
- Hot/cold packs, aromatherapy.
- Partner / doula support.
Medical
- Paracetamol — early labour.
- Entonox (gas and air) — UK very common; fast on/off; no effect on baby; mild-moderate relief.
- Pethidine / diamorphine — sedates baby; less popular now.
- Remifentanil PCA — some UK units.
- Epidural — most effective; requires anaesthetist; slightly increases assisted delivery; ~1-3% headache risk.
- Spinal — for caesarean.
How effective is each option?
Based on Cochrane systematic reviews:
- Epidural: most effective; significantly reduces pain for ~85-95%.
- Spinal: very effective; used for C-section.
- Water immersion: reduces pain perception by ~30-40%.
- Entonox: mild-moderate; varies hugely.
- TENS: modest in early labour; less effective later.
- Opioids: moderate; sedates baby.
- Hypnobirthing / breathing: reduces fear and tension; modest pain relief.
Should I get an epidural?
Pros
- Most effective pain relief.
- Can rest during long labour.
- Effective for back labour.
- Useful for assisted delivery.
Cons
- Requires being still during placement.
- Restricts mobility somewhat.
- Slight increase in assisted vaginal delivery (~1.5x).
- Requires continuous CTG monitoring.
- Small chance of headache (~1-3%).
- Urinary catheter usually needed.
- Can slow second stage (~15-20 min longer pushing).
- Rare complications (infection, nerve injury).
Epidurals are safe, effective, and a valid choice — NOT a “cheat”.
When is it too late for an epidural?
Most units site epidural up to about 8 cm dilation; some site later if anaesthetist available. PRACTICAL LIMIT: needs to be sited BEFORE the active pushing stage. Anaesthetist availability varies — busy unit may have 30-60+ min wait. If considering epidural, ask EARLIER rather than later.
What about water birth / birth pool?
NICE-supported for low-risk pregnancies. Reduces pain perception (~30-40% per Cochrane). Most UK midwife-led units have pools; some hospital units; can hire at home. Sense of weightlessness; calm; movement freedom. Water birth (delivering in pool) safe in low-risk — baby’s diving reflex prevents inhaling water briefly. Must exit if continuous CTG needed.
What is hypnobirthing?
Self-hypnosis and breathing approach to labour pain. Premise: fear creates tension creates pain (fear-tension-pain cycle); reducing fear reduces pain. Techniques: deep breathing, visualisation, positive affirmations, reframing contractions as “surges”. Cochrane 2016 review found modest evidence of reduced pain, anxiety, intervention rates. Compatible with medical pain relief if needed. Typically learned in 5-week pregnancy course.
Do partners / doulas reduce pain?
YES — consistently in research. Continuous one-to-one support during labour (from partner, doula, or supportive midwife) is associated with:
- Shorter labour.
- Lower epidural use.
- Lower instrumental delivery rate.
- Lower caesarean rate.
- Higher satisfaction with birth experience.
Cochrane Hodnett 2017 review of 26 trials, 15,000+ women. NICE NG194 supports use of doulas. Some UK trusts subsidise; private doulas typically £500-2,000.
What is back labour?
When baby’s back is against mother’s back (occiput posterior, OP position) — about 15-30% of labours start this way; most rotate. Pain felt particularly in LOWER BACK because baby’s hard occiput presses against sacrum.
Strategies:
- Counter-pressure (partner pushes against lower back firmly).
- Position changes (all-fours, deep squat).
- Rebozo / scarf techniques.
- Water immersion.
- Hip rotation movements.
Different scenarios — pain plans
Scenario 1: First baby, want minimum intervention
TENS + water + Entonox first-line. Hypnobirthing preparation. Doula support. Have epidural as “in reserve” option. Most first-time low-risk mums achieve this with adequate support.
Scenario 2: First baby, want epidural early
Ask for it when active labour confirmed (~4 cm dilation). Most units happy to site epidural by 4-5 cm. Don’t feel pressured to delay.
Scenario 3: VBAC after previous caesarean
Epidural can be sited (some teams prefer for emergency-CS conversion if needed). Continuous CTG required. Doula support valuable. See /calculators/vbac-success.
Scenario 4: Induced labour at 41+0 weeks
Plan for likely longer process. Discuss epidural early. Mobility restricted by continuous CTG. Bring entertainment. Eat normally in early induction.
Scenario 5: Back labour mid-active phase, planned no epidural
Counter-pressure from partner. Position changes. Birth pool if available. Many women reassess pain plan with back labour; completely fine to switch.
Care guidance — preparing for labour pain
- Antenatal classes — NHS or NCT; helps demystify.
- Hypnobirthing course — evidence-based; 5-week pregnancy course.
- Birth plan with preferences and fallbacks — see /calculators/birth-plan-builder.
- Brief birth partner on counter-pressure, comfort measures, advocacy.
- Hire TENS from 36 weeks.
- Consider doula if budget allows.
- Visit your labour ward — many do tours.
- Pack hospital bag by 36 weeks.
- Practice breathing daily in third trimester.
- Stay flexible — the plan that survives contact with labour is rare.

Frequently asked questions
What pain relief options are available in labour?
NON-MEDICAL: TENS machine; water (bath, birth pool); massage; breathing techniques; position changes; hot/cold packs; hypnobirthing; aromatherapy; partner support. MEDICAL: paracetamol (early labour); ENTONOX (gas-and-air, UK very common); pethidine/diamorphine injection; remifentanil PCA (some UK units); EPIDURAL (most effective; needs anaesthetist); spinal (for caesarean). Different options suit different labours and preferences. The most-prepared birth plans include preferences with FALLBACKS.
How effective is each pain relief option?
Effectiveness ranking (Cochrane systematic reviews): EPIDURAL — most effective; significantly reduces pain for ~85-95% of women. SPINAL — very effective; used for C-section. WATER IMMERSION — Reduces pain perception by ~30-40% in low-risk labours. ENTONOX — Mild-moderate relief; varies hugely. TENS — modest in early labour; less effective later. OPIOIDS (pethidine, diamorphine, remi-PCA) — moderate relief; sedates baby; affects breastfeeding. HYPNOBIRTHING / breathing — reduces fear and tension; modest pain relief. AROMATHERAPY — small effect on anxiety and pain perception.
Should I get an epidural?
Personal choice. PROS: most effective pain relief; can rest during long labour; effective for back labour; useful for assisted delivery (forceps, instrumental). CONS: requires being still during placement (technically harder if active labour); restricts mobility somewhat; slight increase in assisted vaginal delivery (~1.5x); requires continuous CTG monitoring; small chance of headache (~1-3%); urinary catheter usually needed; can slow second stage (~15-20 min longer pushing); rarely complications (infection, nerve injury). NOT a 'cheat' — epidurals are safe, effective, and a valid choice.
When is it too late for an epidural?
Most units site epidural up to about 8 cm dilation; some site later if anaesthetist available. PRACTICAL LIMIT: needs to be sited BEFORE the active pushing stage. ANAESTHETIST AVAILABILITY varies — busy unit may have 30-60+ min wait. KEY DECISION: if considering epidural, ask EARLIER rather than later. You can ask for one then change your mind if labour is going faster than expected. The 'too late' threshold is when you can't sit / stay still long enough for safe placement.
What is hypnobirthing?
Self-hypnosis and breathing approach to labour pain. Premise: fear creates tension creates pain (fear-tension-pain cycle); reducing fear reduces pain. Techniques: deep breathing, visualisation, positive affirmations, reframing contractions as 'surges'. EFFECTIVENESS: Cochrane 2016 review found modest evidence of reduced pain, reduced anxiety, reduced intervention rates. Doesn't eliminate pain (no method does) but can shift perception. Best learned in classes (in-person or online) — typically 5-week course in pregnancy. Compatible with medical pain relief if needed.
What is a birth pool / water birth?
Labouring or birthing in water (warm water immersion). NICE-supported for low-risk pregnancies. Reduces pain perception (~30-40% per Cochrane). Most UK midwife-led units have pools; some hospital units; can be hired at home. PROS: relief; sense of weightlessness; calm; movement freedom. WATER BIRTH (delivering in pool) safe in low-risk; baby's diving reflex prevents inhaling water briefly. CAVEATS: pool may be unavailable if busy; must exit if continuous CTG needed; some pools allow labour only, not delivery. Check your local options.
What's the gas and air I hear about?
ENTONOX — 50% nitrous oxide + 50% oxygen. Inhaled through a mouthpiece. Very common UK; less so US. EFFECT: mild-moderate pain relief, light-headedness, sometimes nausea. SHORT-ACTING (effect peaks 45 seconds after starting to inhale; fades within seconds of stopping) — so you control timing. Use for each contraction. No effect on baby (clears through mother's breathing). NO LIMITATION on duration. PROS: easy to use, on-demand, no needles. CONS: doesn't eliminate pain; some find it makes them feel weird; nausea possible.
What are TENS machines?
Transcutaneous Electrical Nerve Stimulation. Small battery-powered device sends mild electrical pulses through pads stuck to lower back. Believed to: stimulate endorphin release; mask pain signals (gate-control theory). EFFECTIVENESS: modest in EARLY labour; less effective in established labour. CAN BE HIRED for ~£25-50 for whole pregnancy in UK; bought new for £30-80. Use freely; doesn't interfere with other pain relief; doesn't affect baby. Good non-invasive option for first stage; many women combine TENS + water + Entonox.
Will I need pain relief?
Probably yes in some form, but variable. AVERAGES: ~40-60% of UK women use epidural; ~85% use Entonox; ~60% use water. About 5-10% of women genuinely have low-pain labours (luck + temperament + position + preparation). Even women planning unmedicated births often welcome medical relief during transition. PLAN preferences but be flexible — 30-40% of women planning no epidural ultimately choose one. Not failure — informed decision-making in the moment.
Is labour really as painful as people say?
Highly variable. WORLD HEALTH ORGANISATION: labour pain rated by women as more intense than chronic back pain, less than passing a kidney stone, similar to severe burn. INDIVIDUAL variation huge — some women describe 'manageable discomfort'; others 'excruciating'. FACTORS: baby position (back labour worst); pelvic shape; previous experience; preparation; environment; fear / anxiety; cervix dilation rate. INDUCED labour with oxytocin often more painful than spontaneous (faster, more intense contractions). C-SECTION pain different — post-operative recovery has its own pain trajectory.
Can I just have an unmedicated 'natural' birth?
Yes, with preparation and support. SUCCESS PREDICTORS: hypnobirthing / antenatal preparation; one-to-one midwifery care (huge effect); doula support (Cochrane 2017: reduces caesarean, shorter labour, better experience); low-stim environment (dim lights, quiet); freedom of movement; water immersion; positive birth attitude; second + baby; pre-labour low fear. Even with all of these, plenty of women planning unmedicated need / want medical relief — that's NORMAL and not failure. Plan flexibly.
What is back labour and why is it so painful?
When baby's back is against mother's back (occiput posterior, OP position) — about 15-30% of labours start this way; most rotate during labour. Pain felt particularly in the LOWER BACK (rather than abdomen) because baby's hard occiput presses against sacrum. STRATEGIES: counter-pressure (partner pushes against lower back firmly); position changes (all-fours, deep squat); rebozo / scarf techniques; water immersion; hip rotation movements. Most OP babies rotate to favourable position (occiput anterior) during labour. PERSISTENT OP after fully dilated may need instrumental help.
Do partners / doulas reduce pain?
Yes — consistently in research. Continuous one-to-one support during labour (from a partner, doula, or supportive midwife) is associated with: shorter labour, lower epidural use, lower instrumental delivery, lower caesarean rate, higher satisfaction with birth experience (Cochrane Hodnett 2017 review of 26 trials, 15,000+ women). DOULAS specifically — trained labour-support professionals — produce some of the strongest effects. NICE NG194 supports use of doulas. Some UK trusts subsidise; private doulas £500-2,000 typically.
What about the second baby — is it less painful?
Often shorter labour (latent phase usually halved); contractions don't necessarily less painful but more efficient (more progress per contraction); cervix dilates faster (you've done it before). Pushing stage usually MUCH shorter. EMOTIONAL preparation often easier (you know what's coming) — but anxiety about specific past experience may be present. PRECIPITATE labours (under 3 hours total) more common in second + births — be ready to act fast.
What happens if my pain plan goes off?
Plans are guides, not contracts. Flexibility is wisdom. COMMON SHIFTS: planning unmedicated → ultimately choose epidural (30-40% of first-time mums); planning epidural → labour too fast for it (precipitate labour); birth pool full → switch to other relief; baby's position back labour → reassess. The strongest predictor of birth satisfaction is feeling HEARD AND RESPECTED, not which specific choices were made. Your team is on your side.
