Two months after hernia operation, the incision was dull and painful. What's going on?

Generally speaking, one close to the wound may have a tingling sensation when the knife edge recovers, and the other may have a small amount of pleural adhesion. Your situation is usually caused by soft tissue injury and nerve injury.
