Hi, I just had my 5th baby. Last two were born csection and I had both of,my,tubes removed. She was born,3/8/17. My,incision healed nicely. No pain at all, however every 2 to,3 days I get severe abdominal pain near naval area. Naval and above. Its excruciating pain, to where I can barely breathe. It lasts half hour to an hour and,resolves on,it s own.becomes worse when walking. Feels as if someone is twisting a knife. I also have umbilical hernia which doctor said needs to,be removed once,healed. Any ideas what this pain could be caused from?
