I get canker sores once in a while when I'm stressed or going through PMS..., I currently have one on the front of my mouth and on my tongue which I am not worried about.
I noticed my temperature was a little higher than normal and my throat kind of burned, but that only lasted a day. The next day I got the canker sores and one really bad sore behind my wisdom tooth. I recently was able to see it in the mirror and it looks like a big sore that is greyish color in the middle and it's a little swollen around it with a bump hanging down. The sore itself doesn't hurt anymore but the bump does. It's not a boil, but it could be irritated because when I close my mouth, it pinches it. Anyways, i notice to pain is slowly going away, but I am not sure if it's even possible that could be a canker sore because of the color and the location. I have never had one that big but I assume it's because I was under a lot of stress and PMS. I have been doing salt water rinses and oragel. What could it be? I have pictures of it.
