Is It Normal to Have Pain Years After Hernia Surgery?

Persistent pain years after hernia surgery is far more common than most people realize. A large meta-analysis pooling data from over 29,000 patients found that roughly 17% develop chronic pain after inguinal hernia repair, and estimates in the broader literature range from about 11% to over 50% depending on how pain is defined and measured.¹ That means if you are still dealing with groin aches, twinges, or burning sensations years after your operation, you are not imagining things and you are not alone. The condition has specific causes, and in most cases something can be done about it.

How Common Is Chronic Pain After Hernia Repair

“Chronic” in this context generally means pain lasting beyond three months after surgery. At that threshold, about one in five patients reports some degree of ongoing discomfort.² For most of those people the pain is mild, but a meaningful fraction experience moderate or severe symptoms that interfere with daily life. A nationwide Japanese survey tracking patients after laparoscopic groin hernia repair found that pain prevalence did drop over time: about 8% had chronic pain within the first three and a half years, falling to roughly 4% between three and a half and five years out. Even so, pain that “could not be ignored” was still present in 5 to 6% of patients at the five-year mark.³

So the honest answer is that pain can absolutely persist for years, and while it tends to diminish gradually, some people never become completely pain-free. The fact that your surgeon may not have warned you about this is itself a recognized problem in the field. Researchers have argued that chronic pain should be discussed as a standard part of informed consent before any hernia repair.⁴

What Causes Pain That Lasts This Long

Years-long pain after hernia surgery is not one condition with one cause. Research has identified at least three broad categories, and knowing which one applies to you matters because the treatments are different.

The first and most studied category is nerve-related pain. During hernia surgery, three nerves run through or near the operative field in the groin: the ilioinguinal, iliohypogastric, and genitofemoral nerves. Any of them can be stretched, cut, trapped in suture or mesh, or compressed by scar tissue. In one study that systematically classified patients presenting with chronic pain after hernia repair, nerve damage was the single largest category, accounting for nearly half of all diagnoses.⁵ This kind of pain tends to feel sharp, burning, or electric, and it can shoot into the inner thigh or scrotum. It is often described as harder to control with standard painkillers than other types of post-surgical pain.⁶

The second category is pain that comes from the tissues themselves rather than the nerves. This includes inflammation around the pubic bone, a recurrent hernia that was missed, scar tissue buildup, or a tender spermatic cord with a tight sensation in the lower abdomen.⁵ This type of pain is more commonly described as a dull ache or pressure that worsens with activity.

The third involves the mesh itself. Synthetic mesh used to reinforce the repair can trigger a long-lasting inflammatory response. One study examining tissue samples from patients who had mesh placed years earlier found that inflammation around the mesh persisted indefinitely and contributed to ongoing wound-related complications.⁷ In ventral hernia repairs using open mesh, about 13% of patients needed painkillers occasionally at follow-up, with about 4% experiencing persistent severe pain directly attributable to the mesh.⁸

There is also emerging evidence that the nervous system itself can change after surgery. In some patients, the spinal cord and brain amplify pain signals from the operated area long after the original tissue has healed. Researchers have found that this central sensitization contributes to heightened pain sensitivity around the incision site, which helps explain why some people hurt even when imaging looks normal.⁹

Does the Type of Surgery Matter

It does, and this is one of the more consistent findings in the literature. Laparoscopic (keyhole) hernia repair carries a meaningfully lower risk of chronic pain than traditional open repair. An overview of systematic reviews of randomized trials found that laparoscopic approaches reduced the odds of chronic groin pain by roughly 26 to 46% compared to open techniques.¹⁰ A direct comparison of one common laparoscopic method (TEP) versus the standard open Lichtenstein technique showed the difference persisting at five years: about 9% of laparoscopic patients still had chronic pain versus roughly 19% in the open group.¹¹ This gap held up even in older adults, where laparoscopic repair was linked to about 2.5% chronic pain versus nearly 10% for open repair.¹²

The explanation likely relates to the nerves mentioned earlier. Open surgery requires cutting through the layers of the groin directly, placing the three inguinal nerves at higher risk of injury. Laparoscopic approaches work from behind the abdominal wall, largely avoiding those nerves altogether. Additionally, suture-based repairs (without mesh) change the anatomy of the inguinal region by increasing tension, which itself may contribute to chronic pain.¹³

Mesh Weight and How It Is Attached

For patients who have already had mesh-based repair, two surgical details influence long-term comfort. The first is the weight of the mesh. Lightweight polypropylene mesh has been compared to heavyweight mesh in multiple trials. One multicenter randomized trial found that lightweight mesh led to significantly less pain and better quality of life at six months.¹⁴ A separate retrospective study looking at health-related quality of life at one year found a similar trend favoring lightweight mesh for comfort and fewer physical limitations.¹⁵

The second detail is how the mesh is secured. In laparoscopic repairs, mesh can be fixed in place with metal or absorbable tacks, or with surgical glue. A meta-analysis found that glue fixation was associated with significantly less chronic pain than tack fixation.¹⁶ A randomized trial comparing the two methods in TEP repair found that among patients who developed severe pain specifically, glue came out ahead.¹⁷ That said, at least one study found no difference in long-term persistent pain between fixation methods and stressed that a substantial number of patients reported lasting pain regardless of technique.¹⁸ The fixation method matters, but it is not the whole story.

Who Is Most at Risk

A 2024 systematic review and meta-analysis identified several factors that consistently predict who will develop persistent pain after inguinal hernia repair: younger age, female sex, preoperative pain at the hernia site, recurrent hernia (meaning a second repair), postoperative complications, and high levels of early postoperative pain.¹⁹ An earlier large-scale study confirmed that being younger than the median age, having significant pain before the operation, and experiencing any postoperative complication all independently predicted long-term pain.²⁰

The age finding surprises many people. You might expect older patients to fare worse, but the opposite appears to be true. The thinking is that younger patients may have a more robust inflammatory response and heightened nerve sensitivity. It is also possible that younger patients are more physically active and place more demands on the repair site.

Psychological state before surgery also plays a role. A prospective study found that patients who were less optimistic before their operation were more likely to develop chronic pain at four months, as were those who felt less personal control over their pain during the first week of recovery.²¹ Anxiety and depression alone did not independently predict chronic pain in that study, but low optimism did. This does not mean the pain is “all in your head.” Rather, the brain’s pain-processing circuitry is influenced by expectations and mood, and people who go into surgery expecting things to go badly may be primed for amplified pain signaling.

Pain After Hernia Surgery in Women

Most hernia surgery research focuses on men because groin hernias are far more common in males. But when women do undergo groin hernia repair, they appear to be at higher risk for lasting pain. A large Swedish registry study found that 18% of women had chronic postoperative pain, with women facing significantly higher odds compared to men after adjusting for other factors.²² A nationwide Danish register study found that women had higher rates of pain with a negative impact on daily activities at 12 months after surgery, at about 15% versus 9% in men, and were more likely to have moderate-to-severe persistent pain in the long term.²³

Why the difference? The groin anatomy is not identical between sexes. The structures passing through the inguinal canal differ, the shape of the pelvis differs, and the strength of the connective tissue layers differs. These anatomical variations may mean that standard surgical techniques developed primarily on male anatomy do not account well for how female tissues respond to repair.²⁴ Women are also more likely to have femoral hernias rather than inguinal ones, and the Swedish study identified femoral hernia as an independent risk factor for chronic pain in women.²²

Getting a Proper Diagnosis

If you are experiencing persistent pain after hernia surgery, the first step is ruling out a hernia recurrence. Roughly 5 to 7% of repairs eventually fail, and a recurrence can mimic chronic post-surgical pain while being a completely different problem that needs its own repair. Your doctor should also rule out other causes of groin or abdominal pain that are unrelated to the hernia surgery entirely. A clinical review on managing chronic post-hernia-repair pain recommends starting with a thorough physical examination focused on these exclusions.²⁵

Imaging can help. Ultrasound is useful for visualizing the mesh and identifying complications like mesh folding, fluid collections around the mesh, or a recurrent hernia behind or beside it.²⁶ MRI is sometimes added when nerve involvement is suspected or when ultrasound findings are inconclusive. But here is where it gets frustrating for patients: imaging often looks completely normal even when the pain is real and severe. Nerve entrapment and central sensitization do not show up on a scan. The diagnosis often comes down to clinical examination, the pattern of symptoms, and sometimes a diagnostic nerve block that confirms which nerve is involved by temporarily relieving the pain.

Treatment Options From Conservative to Surgical

Clinical guidance recommends a stepwise approach. The first tier is watchful waiting with basic painkillers, especially if the pain is tolerable and not worsening. Many patients find that their pain continues its slow downward drift over time without intervention. Anti-inflammatory drugs and medications specifically designed for nerve pain can be tried next.²⁵

If medication is not enough, nerve blocks are the next step. An injection of local anesthetic near the suspected nerve can confirm the diagnosis and sometimes provide lasting relief beyond what the anesthetic itself would explain, possibly by breaking a cycle of chronic pain signaling. When blocks provide temporary but not lasting relief, some centers offer pulsed radiofrequency or neuromodulation techniques that aim to disrupt the nerve’s pain signals without destroying it.

Surgery is the last resort, but it can be effective. One approach is selective neurectomy, where the surgeon identifies and cuts the nerve responsible for the pain. Another is mesh removal, sometimes combined with neurectomy. A study following patients who underwent mesh removal (about three quarters of whom also had a targeted neurectomy) reported that roughly 64% achieved an excellent or good long-term result at a median follow-up of 18 months.²⁷ Another study of mesh removal with selective neurectomy found a significant improvement in activity scores for the group overall, though three patients actually got worse.²⁸ Mesh removal carries its own risks, including hernia recurrence (about 7% in one series) and, rarely, injury to nearby structures.²⁷ It is generally reserved for patients with severe, disabling pain who have not responded to anything else.

The Role of Physical Therapy

One underused tool in managing post-hernia-repair pain is physical therapy. Rehabilitation protocols are standard practice after knee replacements, rotator cuff repairs, and tendon reconstructions, but they have not been widely adopted for hernia repair despite the fact that the abdominal wall is one of the most dynamic structures in the body.²⁹ A national survey of hernia surgeons found that while many recognized the potential benefits, practical barriers like lack of established protocols and insurance coverage issues have slowed adoption.³⁰

For patients dealing with pain years out, targeted core rehabilitation and graded exposure to activity may help by strengthening the muscles around the repair, improving tissue flexibility, and potentially desensitizing the nervous system. This is an area where the evidence is borrowing from other surgical disciplines rather than proving itself directly in hernia patients, but the rationale is sound and the risk is low. If your pain is partly related to deconditioning or movement avoidance around the surgical site, a physical therapist familiar with abdominal wall issues may be worth seeing.

Preventive Nerve Cutting During the Original Surgery

One of the more provocative developments in hernia surgery is the idea of deliberately cutting the ilioinguinal nerve at the time of the original open repair, before it has a chance to become entrapped or damaged in scar tissue. A randomized controlled trial found that patients who had prophylactic ilioinguinal neurectomy during Lichtenstein repair had significantly lower rates of chronic groin pain at six months: 8% versus about 29% in the nerve-preservation group, with no meaningful difference in numbness or quality of life.³¹ A more recent trial extended this to all three inguinal nerves and found that prophylactic triple neurectomy significantly reduced chronic pain, with only three patients in the neurectomy group developing mild pain versus eleven in the nerve-preservation group experiencing pain of varying severity.³² Another trial confirmed these findings, showing significantly less groin discomfort at six months with prophylactic neurectomy.³³

The tradeoff is that intentionally cutting the nerve causes numbness in a small area of the groin and inner thigh. Most patients in these trials reported that the numbness was tolerable and far preferable to chronic pain. This technique is not yet standard practice everywhere, but it is gaining traction, particularly in open repairs where the nerves are already exposed and visible in the surgical field. If you or someone you know is facing open hernia repair, asking the surgeon about prophylactic neurectomy is a reasonable conversation to have.

Geographic Differences in Reported Pain Rates

An underappreciated wrinkle in the data is that chronic pain rates after hernia surgery vary substantially by region. The same meta-analysis that reported an overall 17% pooled incidence found that European studies reported about 19%, Asian studies about 15%, and North American studies just 6%.¹ Whether this reflects genuine differences in surgical technique, patient populations, pain reporting thresholds, healthcare system follow-up practices, or cultural attitudes toward post-surgical pain remains unclear. It is probably all of the above to some degree. What it means for you as a patient is that the numbers you read online may not perfectly match your risk, and that pain after hernia surgery is defined and measured differently across studies, making exact comparisons tricky. The direction of the evidence is consistent: chronic pain after hernia repair is a real and common problem, regardless of where you live.
