Just a curious question.

So I know during labor, some women tear or the doctor cuts them, (I forgot what they call it) if there isn't enough room. My question is for all you moms who have had that happen. What is the healing process like for that? Do you have to go back and have the stitches removed? Or do they dissolve? I've never had stitches before so I don't know how they feel anyways. Thank you. You don't have to share any stories if you feel it's too revealing. But thank you in advance.
