Torn stitches?

Sarah
I had my baby 3 weeks ago and had a 3rd degree tear with lots of stitches. It seemed like they've healed well, but yesterday I started feeling super raw down there and there's a tiny bit of fresh blood. Just wondering If this has happened to anyone else- I'm so sick of going back to the hospital all the time and don't wanna go in if it's not a big deal!
