Very graphic

I gave birth a month ago and all of a sudden today the left side of my Labia was starting to hurt and I thought it was bc it was rubbing against my pants whenever I walked and then I checked and it was very swollen and puffy

Has anyone else experienced this

Should I be worried?

Should I go to the er???

Update

I think it might’ve been the underwear I was wearing because I changed them and now it’s going down

I’m not sure why it couldve been that tho bc they were just regular underwear and I wore them lots of times before
