A couple days ago I experienced a sore throat leading me to worry if I caught a cold. Luckily it stopped after drinking a plenty of water. Unfortunately after my sore throat disappeared I got a canker sore in my inner lip which made it hard to eat and brush my teeth. Sometimes I accidentally bitten my lip where the canker sore is. I know it will take days to heal this sore especially I bite it sometimes but I hope it goes away soon because now I’m suffering with a headache from this. I hate this canker sore, it’s really pain. Again, hope it goes away soon.
I may ask, is a canker sore related to a cold?
