Black & Blue from Inguinal Hernia
Black and blue discoloration occurs at about 3-5 days after groin surgery and lasts usually about 1 week and then resolves.
This is basically blood from the operation. The more dissection, bleeding, scar, etc., from the operation, then the more likely to have the discoloration. Usually, larger hernias are more likely to have postoperative discoloration. The color is because the blood at the level of the hernia repair/dissection then travels through the tissues as it is pulling from gravity and ends up wherever gravity takes it. It does not imply anything more than it was a difficult/complicated/large/bloody/scarred area.
