I’m sorry that you’ve had issues but it doesn’t change the truth of the statement. Inguinal hernia is a very common problem and I don’t think you realize how many repairs are done. It sucks to be the 1 out of a 100, we understand! But it doesn’t change the fact that 99% of the time, people recover and have no issues.
I am assuming you had the same surgeon for both repairs. A recurrence of a redo has 2 things in common. You and the surgeon. It’s possible that it may be you but I doubt it since you have a successful umbilical hernia repair. Make sure you have a different surgeon for the 3rd to take out the possibility that the surgeon is not good. The nerve issue you can’t do anything about. It’s possible that years later you may get sensation back there. Adhesions in that area shouldn’t be an issue.
Umbilical hernia are different than inguinal and up to 2cm in size, they are repaired with just sutures.
I wish you good luck on the 3rd.
