I had surgery for a hernia in high school. It put me flat on my ass for two weeks, and I couldn't get around with assistance for a solid month afterwards. Do NOT go back to lifting until you're absolutely back to 100%. Wait at least two months, with VERY LIGHT lifting after the first month. The moment you feel discomfort, stop lifting. You'll just get another hernia in the same place, and have to go through the whole ordeal again.
