i have what i believe is a canker sore, but it is one of the biggest and most painful sores i have ever had! along with having the white circle, there is swelling around which i have never had before. It s been hurting especially tonight since it is right on the left side of my tongue, so it has been hitting my teeth, and now sends pain to my right ear, help me, what can i do to treat this at home until it naturally heals on it s own, or should i go see a doctor?
You probably have authors ulcers. Try Xylocaine jelly local application on an SOS basis. If not better, you might need steroid mouth washes.
