OK so the other day, i had trail mix and it contained dried pineapple. ME, knowing pretty well that pineapple causes me to get canker sores in my mouth, had some without really thinking about it cause I thought dried pineapple was better than normal? i dont know.. anyways, ever since then, I have been feeling this cut it feels like on the roof of my mouth. It hurts when I eat anything, and when I drink anything. I have been drinking hot tea lately cause my throat hurts really bad, but the hot tea BURNS the sore on the roof of my mouth so much that it does nothing for my throat. could this cut be from an allergic reaction to the pineapple? cause i have been avoiding them since the last time I had it, i got canker sores on my gums. What can i do to make it heal? ive tried oragel for the pain, which helps a little bit. would salt water help? i dunno.
