HELP!?!?!?

Okay SO, earlier today my boyfriend and I were doing stuff of course and he was fingering me for a good bit but started to get really rough with it and so after a few minutes I asked him to stop and we just continued with other things nonrelated to my vag 😂 anyway i'm home now and it hurts really bad, so I try to take a look and see what happened. THE LEFT LABIA IS HUGE. it's so swollen and it hurts and i'm seriously freaking out. is this going to go away & why did it happen?!
