I have a pinkish gray sore on the side of my tongue, it hurts at times and I have tried all the over the counter remedies, nothing has helped. I have never ever had a cold sore or canker sore, I am 67 years old, never smoked or drank, this is scaring me, I have always been healthy, no illnesses at all, I’m afraid it may be cancer which doesn’t run in my family. I have had this for over a year, I need advice or something, I rarely go to the dr, has anyone had anything like this, please share it with me, thank you so much.
