lately I've been paying a lot of attention to my mouth because I was in fear and I suffer from anxiety and hypochondria. when I look at my mouth I see something that I don't know if it's normal anatomy and then stress and fear destroy me and I have the feeling that something is there even though several of them said that it was nothing. In short, I'm asking if it's a normal anatomy because I've noticed that some people have it and some don't. Sometimes it stings when I eat spicy food but it doesn't hurt and it doesn't sting like this by itself, occasional discomfort when I think about it. I'm 22 years old, I'm male and I'm a smoker. I would like to know if the anatomy is normal and for what reason the feeling of discomfort occurs, how to treat the same?for the last 2.3 weeks it has not changed its color or shape.
