In short
- Surgery is the only way to cure a groin hernia; mesh repair is the usual NHS approach and keeps recurrence low.
- It reliably removes the lump, but a minority of people have lasting groin pain or numbness, so it is not without risks.
- Most people go home the same day and return to light activity within 1–2 weeks, longer for heavy manual work.
- A small, usually not painful hernia can often be safely watched; sudden severe pain, a tender hard lump or vomiting needs emergency care.

What is inguinal (groin) hernia repair?
An inguinal hernia is a lump in the groin that happens when fatty tissue or part of the bowel pushes through a weak area in the muscle wall of the lower tummy. It is very common, especially in men. Repairing it means pushing the contents back inside and reinforcing the weak spot, usually with a synthetic mesh stitched in to lower the chance of it coming back.
Surgery is the only way to cure a hernia — it will not get better on its own, and exercises, trusses or belts only hold it in temporarily. The main reasons to operate are pain, a hernia that is getting bigger or harder to push back, or to reduce the small risk of the bowel becoming trapped (strangulated), which is an emergency.
Not every hernia needs an operation straight away. A small hernia that causes few or no symptoms can often be safely watched, and your surgeon will weigh up your symptoms, your general health and your own preference. Repair removes the lump and the dragging discomfort, but it does not guarantee you will be pain-free, and a small number of people develop longer-term groin pain.
Types & techniques
There isn't one single operation. The right approach depends on you — which is something to discuss with your surgeon.
Open vs keyhole (laparoscopic) repair
| Open | Keyhole |
|---|---|
| One groin cut | Several small cuts |
| Can use local/regional anaesthetic | Usually needs general anaesthetic |
| A little more early pain for some | Often less early pain |
| Similar long-term recurrence | Similar long-term recurrence |
| Often used for a first one-sided hernia | Often preferred for both sides or a recurrence |
Recurrence rates are broadly similar; keyhole tends to mean less chronic groin pain but needs a general anaesthetic and specific surgical experience. The best choice depends on your hernia and your surgeon's expertise.
Preparing for your surgery
- See the operating surgeon, who will examine the lump and confirm whether and when repair is the right choice for you.
- Tell the team about all medicines, especially blood thinners, and about diabetes, heart or chest problems.
- Stop smoking beforehand if you can, as it raises the risk of chest problems, poor healing and recurrence.
- If you are overweight, losing some weight beforehand can lower the risk of complications and recurrence.
- Follow fasting instructions if you are having a general anaesthetic.
- Arrange a lift home and someone with you for the first 24 hours, as you should not drive straight after.
- Plan time off work that matches your job — longer if it involves heavy lifting.
What happens
The operation usually takes about 30 to 90 minutes and most people go home the same day. In open surgery, the surgeon makes a single cut over the groin, eases the hernia contents back inside and places a mesh to strengthen the wall. In keyhole surgery, a few small cuts and a camera are used, and the mesh is positioned behind the muscle.
You will either be asleep under a general anaesthetic or, for some open repairs, numb from a local or spinal anaesthetic while awake. The cuts are closed with stitches, clips or glue. Before you go home the team will check you can pass urine, eat and drink, and walk, and will give you painkillers and aftercare advice.
Is this operation right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- Your hernia is small and usually not painful and the risks of surgery outweigh the benefit for you right now.
- You have an untreated condition (such as a chronic cough, severe constipation or significant obesity) that would raise your risk of recurrence until addressed.
- You are not fit enough for the anaesthetic the planned repair requires.
- Your groin pain is not actually caused by the hernia, so repair would not fix it.
Delay surgery if…
- You have an active infection, including a skin infection over the operation site.
- Your blood-thinning medicine cannot yet be safely managed around surgery.
- You have a chest infection or poorly controlled heart, lung or diabetes problems.
- You are still smoking heavily and could reduce your risk by stopping first.
- You have a temporarily raised risk of straining (for example untreated constipation or a heavy cough).
Alternatives to discuss
- Watchful waiting for a small, minimally symptomatic hernia, with advice on emergency warning signs.
- Treating contributing factors first, such as weight loss, stopping smoking or managing a chronic cough or constipation.
- A support garment or truss as a temporary measure only — it does not cure the hernia.
- Choosing a different surgical technique or anaesthetic better suited to your health.
- The NHS pathway rather than private care if speed is not the priority.
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Anaesthetic choices
The safest option depends on the operation, your health, the facility and your surgeon/anaesthetist. Ask what is planned and why.
Benefits
- Removes the visible lump and the dragging or aching discomfort it causes
- Lowers the risk of the bowel becoming trapped or strangulated
- Mesh repair keeps the long-term chance of the hernia coming back low
- Usually a day case, so most people go home the same day
- Most people return to normal activities within a few weeks
Risks & complications
- Pain, bruising and swelling around the wound for days to a couple of weeks
- A firm swelling or fluid collection (seroma/haematoma) in the groin or scrotum that usually settles
- Temporary difficulty passing urine, especially after a general or spinal anaesthetic
- Tiredness and some discomfort with coughing or straining early on
- Wound infection
- Longer-lasting groin pain, numbness or a pulling sensation
- The hernia coming back over time
- Bruising or swelling of the testicle and scrotum (in men)
- Injury to nearby blood vessels, the bowel, the bladder or the tube carrying sperm (vas deferens)
- Damage to the blood supply of the testicle, very rarely leading to loss of a testicle
- Blood clots in the legs or lungs
- Mesh-related problems needing further surgery
The biggest issues to understand are recurrence and longer-term groin pain. Chronic pain is the main reason some people regret surgery, so it should be discussed honestly before you decide — especially if your hernia causes few symptoms now. Ask your surgeon how many of these they do, which technique they recommend for you and why, and what their plan is if pain persists.
Published figures to discuss
Risk figures vary with the type of hernia, whether it is a first repair or a recurrence, the technique used, and your general health. The numbers below are cautious ranges from UK patient information and surgical literature, not guarantees for any one person. Definitions of 'chronic pain' differ between studies, which is why reported figures vary widely.
| Figure | Reported range | How to interpret it | Source / confidence |
|---|---|---|---|
| Hernia recurrence | Roughly 1 in 100 to a few in 100 over time with mesh; NHS information cites around 1 in 200 | Operations for recurrence have fallen as mesh has become standard (around 8.8% of cases in 2004 to 3.5% in 2019 in one large UK series). Higher with smoking, obesity, infection or non-mesh repair. | NHS — Inguinal hernia repairnhs.ukPublished figure |
| Longer-term (chronic) groin pain | Systematic reviews report chronic pain around 18% after open repair and 6% after laparo-endoscopic repair, but disabling pain is much less common | Most is mild. NHS information suggests around 1 in 20 have ongoing pain and roughly 1–2 in 100 have severe pain that may need further treatment. | NHS — Inguinal hernia repairnhs.ukPublished figure |
| Wound infection | Uncommon, usually low single figures; generally lower after keyhole repair than open repair | More likely with open repair, diabetes, obesity or smoking. | Risk factors for chronic pain after inguinal hernia repair — systematic review (PMC)pmc.ncbi.nlm.nih.govSource-linked context |
| Serious injury to vessels, bowel, bladder or vas deferens | Rare | Numbers are small; this is why an experienced surgeon and informed consent matter. | Risk factors for chronic pain after inguinal hernia repair — systematic review (PMC)pmc.ncbi.nlm.nih.govSource-linked context |
These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
Recovery — what to expect, and when
Most people are up and walking the same day and back to light activity within a week or two. Heavier work and lifting take longer, and a little discomfort can linger for several weeks.
- Soreness, bruising and swelling around the groin wound for a couple of weeks
- A firm lump or fluid collection that gradually settles over weeks
- Discomfort when coughing, sneezing or getting out of bed early on
- Numbness or odd sensations in the skin near the scar
- Tiredness for the first week or so, especially after a general anaesthetic
Aftercare
- Take painkillers regularly at first, then reduce as the pain settles.
- Keep wounds clean and dry, and follow advice on showering and dressings.
- Support the wound with your hand when coughing or sneezing.
- Walk little and often to help recovery and reduce the risk of clots.
- Avoid heavy lifting and strenuous activity until your surgeon says it is safe.
- Eat well and stay hydrated, and manage constipation so you do not strain.
- Do not drive until you can brake hard comfortably and your insurer agrees.
- Keep your follow-up appointment and report any wound or pain concerns.
- Painkillers in stock and a plan for taking them regularly
- Loose, comfortable clothing
- Easy meals and plenty of fluids ready at home
- Someone to drive you home and stay for the first day
- Time off work booked to match your job
- Laxative or high-fibre foods to avoid straining
- The clinic's contact number saved for problems
Scars and how they heal
Open repair leaves one scar in the groin crease, where it is usually well hidden. Keyhole repair leaves a few small scars. Scars are pink and slightly firm at first and usually fade over several months. Some numbness of the skin around the scar is common and may be long-lasting.
⚠ Get urgent help if…
- Severe or increasing pain not helped by painkillers
- A sudden, very painful, hard lump that will not push back — with nausea or vomiting, this is an emergency (call 999)
- Spreading redness, heat, swelling or discharge from the wound (possible infection)
- A high temperature or feeling generally very unwell
- Being unable to pass urine
- A swollen, hot or painful calf, or breathlessness or chest pain (possible clot — call 999)
- Bleeding from the wound that does not stop
Who to contact: your surgeon or clinic first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.
General guidance — it doesn't replace the specific advice your surgeon gives you.
Results & realistic expectations
A successful repair removes the lump and the discomfort it caused, and most people return to normal activity within a few weeks. Mesh repair keeps the long-term chance of recurrence low.
It cannot promise you will be completely pain-free. Most people do well, but a minority have longer-term groin pain or numbness. A good surgeon sets this expectation clearly beforehand and does not present the operation as without risks.
Most repairs last for the long term, particularly with mesh, and the use of operations for recurrent hernias has fallen as mesh has become standard. A hernia can still come back, and the chance is higher with smoking, being significantly overweight, heavy physical strain, wound infection or a non-mesh repair. Looking after your general health helps the repair last.
Combining with other procedures
If you have hernias on both sides, they can often be repaired in the same operation, especially with a keyhole approach. Repair is not usually combined with unrelated procedures, and you should be cautious of being offered add-on treatments you did not come for.
Follow-up & long-term care
Many straightforward repairs do not need a routine clinic visit, but you should be told who to contact and when. Stitches are often dissolvable. You should have a clear route back to the team if you develop wound problems, a suspected recurrence or persistent pain.
- Keep to a healthy weight to reduce strain on the repair.
- Stop smoking to lower the risk of recurrence and chest problems.
- Build back up to heavy lifting and exercise gradually.
- Report any new groin lump or returning symptoms promptly.
Revision and secondary surgery reality
- A hernia can recur and need a second operation; redo surgery is generally more complex than the first.
- Keyhole repair is often preferred for a recurrence after a previous open repair, and vice versa.
- Fluid collections (seromas) usually settle on their own and rarely need draining.
- Persistent chronic pain occasionally needs specialist assessment, nerve treatment or, rarely, further surgery.
Ask your surgeon for their own revision rate, what counts as a revision, and what is included in the written aftercare policy.
What good aftercare looks like
- Clear written advice on pain relief, wound care, activity and when to drive and return to work.
- A named contact and out-of-hours number for wound problems or severe pain.
- Clear emergency instructions for a trapped/strangulated hernia (severe pain, hard tender lump, vomiting — call 999).
- A defined route back to the surgeon for suspected recurrence or persistent pain.
- Realistic discussion that most people do well but a minority have lasting discomfort.
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- Open versus keyhole approach, and whether one or both sides are repaired
- Surgeon's and anaesthetist's fees
- Type of anaesthetic (general, regional or local) and theatre/facility time
- Mesh or device used
- Complexity, including recurrent or large hernias
- Whether it is done as a day case or needs an overnight stay
- Follow-up appointments and the policy if a complication or recurrence occurs
- The surgeon's fee and the anaesthetist's fee
- The hospital/facility and theatre fee
- The anaesthetic type included
- Any mesh or device costs
- Follow-up appointments and dressings/stitch removal
- The cancellation policy
- What happens, and who pays, if there is a complication or the hernia recurs
On the NHS? Groin hernia repair is widely available on the NHS when the hernia causes symptoms or risks complications; private care is often chosen for speed or choice of surgeon, and small usually not painful hernias may be watched on either pathway.
You're entitled to your total cost in writing — including aftercare and any revision — before you decide.
Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- Not being told that a small, usually not painful hernia could be safely watched instead of operated on.
- Chronic groin pain not being clearly discussed before surgery.
- No honest figure for that surgeon's recurrence and complication rates.
- Open versus keyhole presented as a fixed choice without explaining the trade-offs for you.
- No written aftercare plan or clear route back if problems develop.
Marketing red flags
- Describing hernia repair as 'quick', 'simple' or 'without risks' without mentioning chronic pain or recurrence.
- Pushing surgery for a small, symptom-free hernia that could be watched.
- Implying keyhole surgery has no downsides or is always superior.
- No discussion of mesh, alternatives or what happens if it comes back.
Choosing a surgeon safely
- Check your surgeon is on the GMC Specialist Register for this area.
- Make sure they practise at a CQC-registered location, and look for membership of bodies like BAAPS or BAPRAS.
- You're entitled to a two-stage consent process with time to reflect (a cooling-off period). The surgeon who will operate must consent you — not a salesperson.
- Be wary of pressure: time-limited offers, discounts or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including aftercare and any revision — before you decide.
Questions to ask your medical professional
Take this to your consultation. A good surgeon will welcome every one of these.
- Do I need surgery now, or can my hernia safely be watched?
- Would you recommend open or keyhole repair for me, and why?
- Will you use mesh, and what are the alternatives in my case?
- What is my personal risk of recurrence and of longer-term groin pain?
- What anaesthetic will I have, and am I fit for it?
- What is your plan if I still have pain weeks or months later?
- Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
- Will you be the surgeon who carries out my operation, and who looks after me afterwards?
- What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
- What does a realistic result look like — and what can this operation not achieve?
- What are my options, including waiting, doing nothing for now, or choosing a different approach?
- Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
- What is the total cost in writing, including any follow-ups, and how much time do I have to decide?
