question: Hello...A few days ago I noticed a canker sore in my lower right gums, on the outside, facing my cheek. It's very painful, but seems to be getting better eachday.However, other areas of my mouth (all on the same side) seem to be getting sore. My cheek, the right side of my tongue, the gums behind my wisdom teeth, the gums on the other side of the canker sore...Is this normal? Any way to relieve it? It's very unpleasant. Do note I have impacted wisdom teeth on that side. Not sure if it's related, but I feel it's contributing/
