should i go to the hospital?

Lena

my left “flap” of my Labia Majora is swollen. i’m 14. no one else has ever seen my vaginal area, let alone a grown doctor. it itches. i take care of myself, am not sexually active, and shower once a day (sometimes twice). i have walked a lot these past few days and it’s hot? might be a combination of sweat and/or rubbing while walking too much.
