What a perineal tear is
The perineum is the area between the vaginal opening and the anus. During a vaginal birth this tissue can tear when it is stretched strongly. A perineal tear is a common birth injury and does not say anything about whether the birth was good or bad.
More useful than self-blame are three questions: which grade is present, how was the wound cared for, and what does your body need in the postnatal period so healing can begin well?
Grades 1 to 4 and why the classification matters
The grading describes which structures are affected. It does not automatically say how much pain you will feel, because swelling, bruising and individual sensitivity also play a major role.
Perineal tear grade 1
Skin and mucosa are affected. This can burn and be uncomfortable when sitting, but often heals relatively quickly.
Perineal tear grade 2
In addition, the perineal muscles are affected, but not the anal sphincter. Healing can remain noticeable for longer here, especially if swelling or bruising are added.
Perineal tear grade 3 and 4
With grade 3 the anal sphincter is involved, and with grade 4 the rectal mucosa is also affected. These injuries are often called OASI, which stands for obstetric anal sphincter injury. With OASI, repair and follow-up care are particularly important because later problems with controlling wind or stool are otherwise more likely.
A clear overview of OASI, repair and typical follow-up care is available from the RCOG. RCOG: Third and fourth degree tears OASI
Why a perineal tear happens
A perineal tear usually occurs in the second stage of labour, when the head or shoulders are born. Stretch, speed, tissue tension and the mechanics of birth all act together. There is rarely a single trigger.
Situations in which the risk may be higher include instrumental births, a very rapid birth, a prolonged second stage or situations with a lot of pressure on the perineum. This is not a prediction, but an explanation of why perineal protection and good support in the labour room are especially important in those situations.
Care immediately after birth
After birth the perineal area is examined. Smaller tears are either stitched or managed conservatively depending on their location, bleeding and wound edges. Deep injuries must be reliably identified so that suture technique, pain management and follow-up care match the findings.
For OASI, repair usually takes place under suitable conditions, often in an operating room. Afterwards bowel regulation, pain management and structured follow-up are often part of care. ACOG emphasises in its guidance how crucial correct diagnosis and proper repair are for later function. ACOG: Prevention and management of obstetric lacerations
Healing in the postnatal period: what is often normal
Pain, burning and pulling
In the first days pain when sitting, standing up and using the toilet is common. Burning when urinating can happen when urine touches irritated mucosa. For many people this improves noticeably within days; deeper tears usually take weeks to settle.
Swelling and bruising
Swelling is expected after tissue trauma. A haematoma can feel like a hard, tender area and be very painful, even if the tear itself is not very deep. If the pain is very severe, suddenly gets worse or you feel unwell, it should be checked.
Sutures, poking sensations and an unfamiliar feeling
Sutures can poke or pull, especially when sitting. This is often temporary. Some sutures dissolve on their own. If you feel something rubbing or stinging like a small wire, a check-up can help, because sometimes a small adjustment is possible.
Passing stool is often the hardest moment
Fear of the first bowel movement is common. If you tense up or strain strongly, pain often increases. Soft stool is usually the best relief, especially after OASI. This is not a comfort issue but wound protection.
Practical relief in daily life
In the postnatal period, a practical setup that reduces friction matters more than perfection. The goal is to avoid repeatedly provoking swelling and to organise toilet visits in a way that does not create fear every time.
Cooling, positioning, avoiding pressure
- Cooling can reduce swelling and pain in the first days, especially after activity.
- Sitting on your side, short sitting periods and frequent changes of position are often more helpful than long sitting sessions.
- Lying on your side with a pillow between your legs can relieve pressure if lying flat is uncomfortable.
Toilet visits without extra strain
- Lukewarm water over the intimate area can reduce burning when urinating.
- Gentle cleaning is better than vigorous wiping, especially when the wound is sensitive.
- If you notice that you are straining, a pause is often more sensible than forcing pressure.
Measured activity instead of all or nothing
Total immobility makes many things harder: the bowel becomes slower, pelvic floor awareness can feel less reliable, and mentally the day can feel more cramped. Short, regular walks are often the better strategy. If you feel noticeably worse in the evening than in the morning, your day’s load was probably too high.
Pelvic floor, postnatal recovery and intimacy
The pelvic floor is stressed after every pregnancy, regardless of whether a tear occurred. After a perineal tear it can be more sensitive or feel unstable. Postnatal recovery is then less a matter of training and more a matter of dosing: start gently, watch symptoms and do not work beyond pain.
After OASI, structured follow-up is especially important because problems sometimes only become apparent when everyday life becomes more active again. The NHS summarises follow-up care, everyday life and typical recommendations well. NHS: Your body after the birth
Scar tissue can be dry, sensitive or less elastic in the first weeks. If you want to have sex again, a slow start, enough lubricant and a point at which touch and stretch feel safe can help. If it still pulls, burns or triggers fear, waiting is completely reasonable.
Bathing, showering and warmth
Gentle warmth can feel soothing if it relaxes the area and does not irritate it further. A short warm bath is helpful for some, as long as the wound is dried properly afterwards. Long baths are less ideal, especially if the skin becomes soggy or the area burns more afterwards.
Showering is usually possible early on, as long as the water flow is gentle. If cooling helps you more than warmth, that works just as well. What matters is not the one right method, but what calms your wound best in everyday life. Hillingdon: Caring for the perineumCUH: Third and fourth degree perineal tears
What happens if the wound opens?
A small wound opening is not a reason to panic, but it should be looked at. Depending on size, pain and healing progress, the area may be cleaned, checked or treated further. Not every wound needs a new stitch immediately.
If you notice the edges pulling apart, the area suddenly starts weeping or the pain clearly changes, a timely assessment is sensible. The earlier it is seen, the better the next step can be chosen.
When pelvic floor exercises become useful again
Gentle pelvic floor exercises can be helpful after birth, but not as strength training with pressure. If the wound is very fresh, very painful or clearly swollen, rest is more important at first. Once it feels right, a cautious start can be sensible, ideally in the way your midwife or doctor advised.
If tightening causes more pain, pulling or downward pressure, that is a sign to slow down and have the area checked again.
Warning signs: when you should not wait
Many complaints are uncomfortable but expected. These signs point more towards a complication or towards a situation that should be medically reassessed.
- Fever, chills or a clearly unwell feeling
- Wound becomes noticeably red, hot, weeps or smells unpleasant
- Pain becomes clearly worse over days instead of better
- Severe, increasing swelling or a tender lump that changes quickly
- New problems controlling wind or stool, especially after OASI
If you are unsure, early contact is usually the shorter route. Many problems can be stabilised more quickly in the postnatal period than later under prolonged stress.
Prevention for a future birth
No one can prevent a perineal tear with certainty. However, there are measures in studies that are linked with fewer severe injuries or fewer episiotomies and that many people can reasonably use.
Perineal massage during pregnancy
A Cochrane review describes that antenatal perineal massage can reduce the likelihood of perineal trauma, especially episiotomy, and that persistent perineal pain is reported less often. Cochrane: Antenatal perineal massage
Warm compresses and perineal support during the second stage
A Cochrane review on techniques in the second stage finds evidence that warm compresses and perineal support can reduce the risk of severe perineal trauma. Cochrane Library: Perineal techniques during second stage
What you can practically take from this
- Discuss during pregnancy how perineal protection is handled in the labour room.
- Ask whether warm compresses are possible.
- If you had an OASI, plan the next birth early in pregnancy.
Myths and facts about perineal tears
- Myth: Severe pain always means a severe tear. Fact: Swelling or a haematoma can cause severe pain even with smaller tears.
- Myth: A perineal tear always heals quickly and completely without follow-up. Fact: Many heal well, but after OASI structured follow-up is essential.
- Myth: You just have to get through bowel movements. Fact: Straining and fear often increase pain; soft stool and rest are usually the better approach.
- Myth: Scar care means constantly doing something. Fact: At first protection and rest matter; later gentle mobilisation can help, while overactivity irritates tissue.
- Myth: Foul smell is always normal in the postnatal period. Fact: A foul smell together with pain or fever can be a warning sign.
- Myth: Movement is always bad after a perineal tear. Fact: Measured movement is often helpful; overloading is the problem.

Conclusion
A perineal tear is a common birth injury with very varied severity. For most people, it improves step by step when pain, toilet visits and daily life are supported realistically, and for deep tears, structured follow-up is especially important. If you remember two things, watch the trend over several days and take warning signs seriously. Seeking help early is not an overreaction but sensible postnatal care.
