Cold sore or canker sore

Answer 1

To me, both are pretty bad, but a canker sore is always worst! Cold sores can hurt sometimes and are a pain to have on the lip, especially because of it being un-comftorable! Canker sores hurt very bad, I would know, as I get them a lot! They sting in your mouth and it's hard to eat things and especially the pain they inflict on people who have them when they get up in the morning!
