Stitches gone wrong

Hi! I had a baby two weeks ago and I had a first degree tear. Days later I was in so much pain and things didn’t seem right so I got a mirror to look in that area. I noticed that my left labia was missing. My right one was there but my left wasn’t, when I looked inside My vagina I saw that It was inside deep down. They stitched me up but also stitched my labia down. This whole time I knew something was wrong because I was in pain and because I felt a pulling sensation.

When I told my doctor she didn’t believe me because she said that’s not something that can happen. So she saw me a week later, and when she did she noticed that they stitch it down so she had to go down and cut me and cut the stitches. It hurt so bad.

I went home and realized it still wasn’t better, two days later I went back and she had to cut me again.

Is this normal? I’m in so much pain and still everything isn’t where it should be. Can I sue for this?
