I've had 3 ventral and 1 umbilical hernia. I am currently recovering from getting 2 ventral and the umbilical hernia repaired. The other ventral hernia was repaired two years ago. The ventral hernias were between my the top of my rib cage and my belly button. I was actually shocked to find out I had an umbilical hernia since I had no symptoms. During my last pregnancy, I felt a slight protrusion in the same area as my previous ventral hernia. My OB said to go see the surgeon again b/c that's what she thought it was. The surgeon told me to see him after I delivered the baby, so I did. At first he didn't think I had a hernia after all (I was relieved), but sent me for a CT scan to make sure. Sure enough, it showed one ventral hernia. So, when I went in for a "quick" surgery and 1-day hospital stay, you can imagine I was shocked when he told me how many he found. He put a large piece of mesh over my entire ab area, and I was in hospital for 4 days! Anyway, 4 weeks later, I'm starting to feel like my old self again. By the way, he said my pregnancies did it to me. He also said I had a weakness in that area where the hernias were. He said I could have been born with that weakness and the pregnancies may have caused more harm.
I also had a hospital roommate for a short time, and she had an umbilical hernia. Her baby is 3 months old. This lady went on a trip with her husband, went to a yoga class and was in a lot of pain when her belly button popped out. They immediately flew home and went to the ER. She was in the hospital room waiting for an OR to open up. So, in her case, she had really bad pain out of the blue and got immediate surgery. I'm not sure how she was able to fly back her from her vacation if she was in that much pain, but somehow she did. She went home the same day as her surgery.
It's good that you're seeing your doctor just to be sure. Good luck, and let us know what your dr. says.
