Very unusual tongue growth
As the title states, I have an unusual looking tongue growth that popped up about 2 weeks ago. I say unusual because I've searched every picture imaginable online for tongue growths, cancer, etc and nothing matches it really. It is a little painful and its on the side on my tongue... kinda wrapping around to the top slightly and along the side. It's flat like a disc-shaped, not hard, fleshy and foldable edges that sometimes get caught in my teeth when I swallow water or pills, and painful when that happens. The top part is sore to the touch as well.
Is this the best place to ask about it? I have an appointment next week at an ENT office, but in the meantime I'm worried its something serious, like cancer, and wanted to know if anyone has seen anything like it before. Thank you for any insight anyone can give me!!
