My mouth???? may be tmi

Okay so i’m going on day three of what I THOUGHT was a sinus infection up until yesterday afternoon. the left side of my face is swollen and my bottom wisdom tooth is killing me.... and also my tongue looks like this... I already have a geographic tongue and it easily gets irritated but it has never been this bad before... any ideas? i can’t eat and it hurts to even speak :( **** also it’s very unlikely that it would be and STD, i’m engaged to and have been with the same guy for three years now and have a child with him!
