Momma Makeover - Omaha, NE

I had a mommy makeover in October and I am still having complications. My belly button starting getting a big blister on it about 2 months ago. Come to find out my body was trying to fight something off. My doctor couldn't find anything for about a month. One month ago he found a stitch that was wrapped around my muscle and pulled it out. It was about 2 feet long. It hurt so bad. I am still trying to heal up from that. I am very worried that the stitch was suppose to be there. I keep reading the muscles are suppose to be stitched together. Can someone please let me know if that's true. Thanks
