Hi, so I have canker sores; i found the name on the internet. Ena it's recurring. Befit, i'd usually put salt or lemon on it and it disappears in a matter of days. Gin ahun it gets even worse when i try to treat it. It expands and it swells. I have to rn, and they're near to each other, if they keep expanding they'll join and form a bigger sore which might take long to heal. It has happened before. Anyways, nothing i saw on google helped so i want to know if anyone has a remedy for it that worked for them. Thanks on advance.
