Someone please help! This pain is terrible :'(?

For about four to five days, I've had this stinging, burning sensation on the edges of my tongue. Only on the edges of my tongue. It hurts to the point where I can barely eat or drink and mouthwash almost forces me to cry. The edges seem to be red and a bit swollen, but idk. I'm not a doctor. Can someone please help me?! I need this pain to go away ASAP! Also, Idk if this has anything to do with it, but I have a healing canker sore on the inside of my lower lip.
