I have a raised ridge inside my left cheek that started mid-cheek and is now alongside my nose and down, like it's been moving. This is the second week now. It's about 1/4 inch wide and 2 inches long. No trauma except chomped on my tongue eating popcorn, kernal slipped, tongue bled, two small holes. Healed, now this. INSIDE my cheek, no rough patch in mouth, nothing coming to surface like a boil. Any ideas?
