You'll do fine, Vonny. I've had one of those umbilical hernias repaired and am working toward getting scheduled for surgery on three more hernias in my abdominal muscles. One of mine has gotten so big, it looks like I have a volleyball under my clothes.
My mom, BBB also had a hernia repair last year. It was done as an outpatient surgery and she barely felt it afterwards.
The hardest part will be remembering no heavy lifting, bending or stretching for a couple weeks after surgery. After that, it will no longer hurt when you do those things like it did prior to surgery.
