Realistic expectations
It is completely normal to feel worried about pain after surgery, especially if you have heard difficult stories from others. But the reality with inguinal hernia repair — whether keyhole or open — is genuinely encouraging. It is one of the less painful operations in terms of what you feel afterwards. The groin simply does not have as many pain-generating structures as, say, the chest or the major abdominal organs.
The vast majority of patients describe their recovery as mild to moderate discomfort — not severe pain. Most people are up and moving the same day or the day after surgery, manage comfortably with standard tablets, and feel well enough to get on with light daily life within a few days.
That said, everyone is different, and the experience does vary depending on whether you had keyhole or open surgery, and on your own pain tolerance. Understanding what to expect — and knowing what would be unusual — means you can manage your recovery with confidence rather than worry.
Pain after keyhole (laparoscopic) hernia repair
After keyhole repair, you will likely notice two quite different types of discomfort:
Wound discomfort
The three small port sites (each around 5–10 mm) cause very little wound pain. Most people find them mildly tender if you press directly on them, but not particularly bothersome otherwise. This type of discomfort is almost always well-controlled with paracetamol alone.
Shoulder-tip pain from the gas
To do keyhole surgery, the surgeon inflates your abdomen with carbon dioxide gas to create working space. After surgery, some of that gas is left behind temporarily and sits under your diaphragm (the muscle below your lungs). This irritates a nerve there, which — confusingly — causes pain felt in your shoulder tip rather than your abdomen. This can be quite uncomfortable for the first day or two but resolves on its own as the gas is absorbed, usually within 24–48 hours. Moving around (walking upright) helps the gas disperse faster. A heat pack on the shoulder is soothing while it lasts.
Pain after open hernia repair
Open repair involves a cut of about 5–7 cm in the groin, which typically causes more wound discomfort than the small port sites of keyhole surgery. You may notice it most when standing up from sitting, walking briskly, or coughing. But there are some reassuring things to know:
- There is no shoulder-tip gas pain with open surgery
- The wound discomfort is well-localised — it is in one spot — and is manageable with regular paracetamol and anti-inflammatory tablets
- Pain is usually at its worst in the first 2–4 days and improves steadily from there
Many patients who have had open repair say they were pleasantly surprised. Yes, it is uncomfortable — but not the severe pain they had braced themselves for.
How pain changes over the first two weeks
Day of surgery and day 1
You will have been given pain relief in the operating theatre — local anaesthetic in the wound area, anti-inflammatories, or short-acting medication through your drip. As this wears off over the hours after surgery, you may feel more discomfort — typically a groin ache and, after keyhole surgery, shoulder pain. The key is to take your pain relief regularly, not just when the pain gets bad. Regular paracetamol and ibuprofen (if appropriate for you) keep a steady level in your system. Most people rate this day as about 3–5 out of 10 with medication — uncomfortable, but manageable.
Days 2–4
The shoulder gas pain settles, and groin discomfort starts to improve. Getting up from lying down or standing up from a chair may still cause a sharp ache. Regular paracetamol (1g up to four times daily) is usually enough at this stage, with ibuprofen as needed. Most people are comfortable moving around the house, watching TV, and doing light tasks. Pain is usually around 2–4 out of 10.
Days 5–7
Most people feel noticeably better by this point. You may still want paracetamol a couple of times a day but will not need it around the clock. A walk outside for 15–20 minutes is usually comfortable. The groin is still tender if you press on it directly. Scrotal bruising or swelling may be at its most visible around this time (more on that below), but this is normal.
Week 2
Most people need very little or no pain relief by the end of week two. The groin may still feel tender with specific movements — climbing stairs, getting in and out of the car. You will be moving around much more freely. The wound is healing well and most people comfortably return to light desk work during this week.
Scrotal bruising and swelling — normal and expected
After groin hernia repair — particularly if the hernia was on the larger side or had extended toward the scrotum — it is very common to develop bruising and swelling of the scrotum in the days after surgery. This can look alarming, but it is a normal result of the dissection during the operation and fluid tracking downward under gravity.
- Bruising (blue-purple discolouration) of the scrotum typically peaks around days 3–5 and fades over 1–2 weeks
- Scrotal swelling may feel firm and tender — it usually settles on its own over 2–6 weeks without needing any treatment
- Snug-fitting underwear (briefs, not loose boxers) and elevating yourself when resting help reduce swelling
If the scrotum becomes extremely painful, feels very hot, the skin looks red, or you develop a fever, contact your surgeon. Those things could point to infection or a blood collection (haematoma) that needs attention.
Your pain medication guide
Paracetamol
This is the main pain reliever for most people after hernia repair. Take 1g (two 500 mg tablets) up to four times a day (every 6 hours), even if you are not in severe pain — taking it regularly keeps a steady level in your system and stops pain from building up. Do not take more than 4g in 24 hours.
Ibuprofen or naproxen
Anti-inflammatory tablets work well for hernia repair because some of the discomfort is inflammation-related. Always take them with food. They are not suitable for everyone — avoid them if you have kidney problems, a history of stomach ulcers, or are on blood thinners. Your surgeon will let you know if they are appropriate for you.
Stronger pain relief (codeine, oxycodone)
Most people do not need opioid-based pain relief after a planned hernia repair. If you are given it, use it for as short a time as possible — 2–3 days at most. One important note: these medications cause constipation, and straining to pass a bowel motion after hernia repair is both uncomfortable and hard on the repair. If you are taking them, ask your surgeon about a stool softener to take alongside.
When to contact your surgeon — warning signs
Please contact your surgeon or seek medical attention if you notice any of these:
• Temperature above 38.0°C
• The wound becomes increasingly red, hot, swollen, or starts to discharge fluid
• Your pain is getting worse after day 3 — it should be improving, not worsening, by then
• You cannot pass urine (more common in older men after open repair under local anaesthetic)
• A new bulge appears where the hernia was — this could mean recurrence or a blood collection
• A firm, painful, enlarging swelling near the wound (this may be a haematoma — a collection of blood)
• Nausea and vomiting that persists beyond 24 hours after surgery
Frequently asked questions
In our experience, almost always less. Most patients say recovery was easier than they anticipated. The groin tolerates this kind of surgery well, and modern keyhole technique minimises the amount of tissue disturbed. If fear of pain is holding you back from getting assessed, please know that pain really should not be the deciding factor here.
Most people get through recovery with paracetamol alone or paracetamol plus ibuprofen. Strong opioid pain relief is not needed by the majority of patients after planned hernia repair, and is not routinely prescribed.
The gas used to inflate your abdomen during keyhole surgery is left behind in small amounts after the operation. It collects under your diaphragm and irritates a nerve there (the phrenic nerve), which causes pain felt in your shoulder. This is normal, very common, and typically resolves within 24–48 hours. Walking and avoiding lying completely flat helps it disperse faster.
Yes, quite common. The groin has several small nerves that may be gently disturbed during the repair. Numbness, tingling, or altered sensation in the groin, inner thigh, or scrotum after hernia surgery is normal and usually improves over several months. If the numbness is severe or bothering you significantly, mention it to your surgeon at your follow-up.
Most people feel like themselves again within 4–6 weeks after keyhole repair, and 6–8 weeks after open repair. Full recovery — including getting back to heavy lifting and strenuous exercise — is typically 8–12 weeks. Some residual sensitivity around the wound can persist for a few months and is normal.
A small number of people do experience ongoing groin discomfort after hernia repair, particularly nerve-related pain. If you have had significant persistent pain beyond 3 months after your operation, please bring it up with your surgeon. Most cases of chronic post-repair groin pain can be managed — with time, physiotherapy, or targeted treatments — but it is important to have it assessed rather than simply tolerating it.
