It sounds as if you have tried many avenues for treatment. The occurrence of severe chronic pain
after hernia repair
is rare, occurring in less than 1%. It may be due to damaged of trapped nerves or tissues at the operation site. By re-operation, the surgeons will be able to examine the repaired hernia site and may be able to diagnose the problem and correct it possibly by releasing trapped or tight tissues.
