Trying to figure out what type of a doctor I should go see...I possibly have discoid lumpus according to previous doctor visits. At certain times of the year I get a "red rash around my mouth and what looks like might be a cold sore in the corners, but it is not a cold score. After feeling something weird with my tongue in the inside part of my cheeks, I looked in the mirror and starting from the corners of my mouth where there is a raised bump going towards the back of my inside cheek I now have what looks like a "raise tissue line" and it's on both sides.
