Emergency bite !!!!!!

Long story short -

Got with someone last night and they may have bit my lip too hard without realising (we were both drunk)

I’m in work today and realised my top lip is purple (!!)

I’m going out for a meal tomorrow with my dad too - there’s no way he can see it!

Please help I need to get rid of it ASAP

-doesn’t hurt or anything it’s just very purple and slightly swollen
