About 7 days ago I noticed a metallic taste in my mouth that would go away only when I brushed my teeth or ate something, then it would return.
A few days later I got a really small bump on my inner cheek, down the back near my back teeth, it's kinda white, and has a red ring around it, but that could just be my cheek colour it doesnt hurt. The same day I also got a ulcer below it on my gum, and the opposite side of my tongue is tingling and feels a little weird. Kind of numb.
I brush my teeth twice a day, I use mouth wash one of those times, and I floss.
I haven't been eating an unusual amount of sugar..I've been drinking alot of water.
What could be going wrong??
