Should I be worried?

Every now and then in between my legs (my vigina) will sting. Not a lot, and it usually goes away, but while at work this morning it was kinda bad and hasn’t really gone away. It feels almost like I peed myself but I know I didn’t. It also feel slightly swollen while walking around. Should I wait to see if it goes away or should I tell my mom?

Update: told my mom she thinks it’s a yeast infection. So I’m going to try cranberry juice and some over the counter medication
