Swollen Labia

So the other day i went to use the bathroom and noticed this medium sized bump on the right side of my labia majora . I went online and read a hot compress works and so does a cold compress . I’ve tried both , but the next day it just got bigger . I literally have trouble walking and sitting down . It’s flesh colored and hurts when i touch it . Its like a stinging sensation when i’m sitting still . It’s made it very uncomfortable to sleep in ANY position and it seems that wearing underwear or pants in general just make it hurt more . Can you guys please help me ?
