In short
- The scar of a caesarean crosses sensory nerves of the abdominal wall. The area being numb, tingly or hypersensitive is a direct consequence of that.
- Persistent pain decreases with time: in a meta-analysis of 48 studies it went from 15.2% at three months to 9.5% at six and 5.0% at a year.
- 🔑 When the pain is moderate or severe, in more than half of the cases examined there was a trapped nerve. It is not “how the scar turned out”: it is a specific diagnosis.
- Numbness is not just a nuisance: it is a predictor. Women with numb areas were more likely to develop chronic pain.
- An emergency caesarean and a second incision over the same area increase the likelihood of persistent pain.
- ⚠️ Not all pain after a caesarean comes from the wall. It can also have a uterine or pelvic origin, and that is investigated differently.
- Getting it looked at makes sense when the pain is limiting, when an exact point appears or when the pattern changes. There is no need to wait a year.
That a caesarean scar goes on being troublesome months later, or that the area around it is numb, is frequent, described and explicable. In a series of 690 women operated on through a Pfannenstiel incision, one in three reported some pain in the area two years later; in 7% it was moderate or severe. And in more than half of those examined for pain of that intensity, the cause was a trapped nerve, which is a diagnosis with a treatment.
This page explains where each thing comes from — the pain, the numbness, the pulling — how long it usually lasts, what makes it more likely and in which cases it is worth getting it looked at rather than waiting.
This page sets out one of the sections of the caesarean sequelae, where the rest of the picture is.
Why the area goes numb
The usual caesarean incision — the Pfannenstiel, transverse and low — crosses the path of the nerves that give sensation to the lower abdomen, the groin and the upper part of the pubis, mainly the iliohypogastric and the ilioinguinal.
When they are cut or become caught up in the healing, the skin that depended on them stops reporting in the same way. Hence the three sensations described:
- A numb area above or around the scar, sometimes fairly extensive.
- Tingling or a shooting sensation, above all on being brushed or on stretching.
- Hypersensitivity: an area where the touch of clothing is felt more than it should be.
What usually happens is that it improves during the first year, as the surrounding innervation reorganises, and that a smaller, less obvious area is left. That it does not fully recover is possible and does not mean anything has gone wrong.
How long the pain lasts: what the figures say
Here it is worth giving two numbers that measure different things, because otherwise they look contradictory.
What happens over time. A meta-analysis of 48 studies on persistent pain after caesarean found (Wang, 2025):
| When | With persistent pain |
|---|---|
| 3 months | 15.2% (95% CI 12.2-18.6) |
| 6 months | 9.5% (95% CI 7.0-12.8) |
| 12 months | 5.0% (95% CI 2.7-9.1) |
🔑 The reading that matters is none of the three figures on its own, but the slope: the pain subsides. That is exactly what someone eight months in with discomfort, not knowing whether it is going to be like this for ever, wants to know.
⚠️ One qualification that changes the number for a British reader: at twelve months, the figure was 7.6% in high-income countries against 1.3% in low- and middle-income countries. The global average is too low here.
What turns up if you ask directly. In a series of 866 women with a Pfannenstiel incision — for caesarean or for hysterectomy — who answered a questionnaire at two years, 223 of 690 (one in three) reported some pain in the area, moderate or severe in 7% and limiting daily activities in 8.9% (Loos, 2008).
They do not contradict each other: they ask different questions. The meta-analysis pools studies with strict definitions of chronic pain; the series records any discomfort reported, including mild, and in a population that includes another operation besides the caesarean. The honest thing is to publish both with their scope, not to average them.
The trapped nerve: the diagnosis worth knowing about
This is the finding with the most practical consequences on the whole page.
In that same series, the women with moderate or severe pain went on to physical examination. In 17 of 32 — more than half — nerve entrapment was found (Loos, 2008).
What it is. A sensory nerve caught up in the scar tissue or compressed as it passes through the wall. How it presents, fairly characteristically:
- An exact point at a specific place on the edge of the scar, which reproduces the pain when pressed.
- Pain that radiates towards the groin, the pubis or the inner thigh.
- Pain that worsens with exertion or on stretching and improves on bending forward.
- Often, a numb area right beside it.
🔑 It matters because it is a diagnosis with a treatment, and because the alternative — assuming that “that is how the scar turned out” — leaves the patient with no way forward.
What can be done, once confirmed. The approach is stepwise and goes from the least to the most:
- Injection with corticosteroid and local anaesthetic at the point, which as well as treating confirms the origin: if the pain settles on injection, the diagnosis holds.
- Surgical release of the nerve, when it is caught up in the scar tissue.
- Neurectomy, that is, dividing the affected nerve.
- Excision of the scar, when the problem is in the scar tissue itself.
- Medication, alone or alongside the above.
Not all wall pain requires surgery, and the order is decided by the examination and by the response to each step.
⚠️ And there are two predictors from the same work worth bearing in mind: numbness and having had more than one operation through the same incision were associated with more chronic pain, as was an emergency caesarean.
Not all pain comes from the scar
It is the distinction that stops you staring at the wall when the problem is behind it.
A caesarean is surgery on the uterus, and that plane has possible consequences of its own. A 2026 review of uterine closure reminds us that caesarean is associated with an increased risk of pelvic pain, abnormal bleeding, secondary infertility and implantation problems in later pregnancies, and that much of that depends on how the uterus was closed, not the wall (Bujold, 2026).
How they are told apart in practice:
- Points to the wall: pain you can locate with one finger, that is reproduced by pressing the scar, that changes with movement or posture.
- Points to another origin: deep, diffuse pain, related to the period or to sex, or accompanied by abnormal bleeding.
- ⚠️ And one particular pattern stands on its own: a lump in the scar that hurts in time with menstruation. That is scar endometriosis, and it is investigated separately.
What can be done
If what predominates is a stuck scar and tightness, massage can free and release the scar and improve the discomfort. It is reasonable as a first measure. It is set out on the conservative route page.
If there is an exact point that reproduces the pain, the approach is different and starts by confirming the origin. It is not a matter of time or of tolerance: there is an identifiable cause, and with it there is treatment: injection, release of the nerve, neurectomy, excision of the scar or medication, in whatever order the examination decides.
And surgically releasing the scar improves the pain in some cases, even when there is no clear entrapment: freeing the adherent plane relieves the traction that was maintaining it.
⚠️ There is one scenario worth naming, because it exists. Sometimes, once the options above have been exhausted or ruled out, what is left is chronic pain with no locatable cause, and then the treatment is symptomatic: it is treated with medication, with no procedure to correct anything, because there is nothing specific to correct. Saying so is not giving up: it is stopping a patient having one operation after another in search of a cause that is not there.
On the appearance of the scar — which is a different problem from the pain — the centre’s scar protocol works, and it can be applied to a caesarean scar with no surgery beforehand.
And where surgery is indicated for another reason — excess skin, a shelf — the old scar is excised as part of the procedure and the plane is released. It is covered in how the surgery is decided.
🚨 Get it looked at without delay if the pain limits daily activity, if a very localised point appears that reproduces the pain when touched, if the pattern changes or if it comes with a lump that is growing.

Frequently asked questions
Is it normal for my caesarean scar to hurt years later?
It is frequent. In a series of 690 women with a Pfannenstiel incision, one in three reported some pain two years later, and in 7% it was moderate or severe. That it is frequent does not mean it has to be put up with: when the pain is severe, in more than half of the cases examined there was a specific cause.
Why is the area above my scar numb?
Because the incision crosses the path of the nerves that give sensation to that area. It is a direct consequence of the surgery, not a sign that anything was done wrong. It usually improves during the first year and a smaller area may be left not fully recovered.
Does the numbness recover?
In general it improves over the months, as the surrounding innervation reorganises. Some women keep a less sensitive area permanently, with no consequence beyond that.
I have a point on my scar that gives me a shooting sensation if I touch it — what is that?
That pattern — an exact point that reproduces the pain and sometimes radiates it towards the groin — is what makes one think of a trapped nerve. It is a specific diagnosis and deserves examination, rather than being taken as final.
Is there anything I can do myself to improve it?
Massaging the scar helps when what there is is adhesion and tightness. It does not replace assessment when there is severe pain or a localised point, because there the first thing is to know where it is coming from.
Does this pain mean I need surgery?
Not automatically. Much wall pain is managed without surgery, and a good deal of it subsides during the first year. Surgery comes into the conversation when there is something to correct — excess skin, a shelf, an identified cause that justifies it — and always after an individual assessment.
Does it matter that the caesarean was an emergency one?
Yes, it appears as a predictor of persistent pain, as does having had more than one operation through the same incision and having noticed numbness. They are known factors, not something that could have been avoided at the time.

Book your consultation
If you have had discomfort in the scar for months and do not know whether it is normal or whether there is something to look at, an examination clarifies it quickly: it is checked whether there is adhesion, whether there is a point that reproduces the pain and whether what you feel fits the wall or points somewhere else. Out of that comes what to do, which is often not surgery.
