Hernia repair surgery is meant to fix weakened or torn tissue in the abdominal wall, but 10% to 30% of patients continue to have chronic pain after surgery.

One major cause is nerve irritation or entrapment. Small nerves can become compressed by scar tissue, inflammation, or surgical mesh, leading to sharp or burning pain that doesn’t go away. Mesh-related complications can also cause stiffness, nerve irritation, or inflammation. In some cases, mesh can shift or contract, leading to new or worsening pain. Scar tissue and chronic inflammation may also create tightness or sensitivity, while muscle weakness after surgery can contribute to discomfort.

Certain factors increase the risk of chronic pain. Younger patients, particularly under 40, are at higher risk, possibly due to more sensitive nerve function. Larger or more complex hernias, open repairs, and pre-surgery pain also increase the chances of ongoing discomfort. Some people may even have inflammation or sensitivity to surgical mesh.

If pain persists, there are options beyond medication. Nerve blocks, radiofrequency ablation, and regenerative medicine can help manage symptoms without additional surgery. For severe or persistent nerve pain, spinal cord stimulation (SCS), dorsal root ganglion (DRG) stimulation, or peripheral nerve stimulation (PNS) may provide long-term relief. These block pain signals before they reach the brain and are reversible and adjustable, making them safer alternatives to repeat surgery.

Hernia repairs are often necessary, but they’re not without risks. If you're considering surgery or dealing with chronic pain after a repair, exploring all treatment options and getting multiple opinions can help you find the best path to lasting relief.
