Red circular rash inside cheek?

[MeGustaPasta]

Hey all,

For some background info I’m 25, male, and not a tobacco user (I did smoke socially for a year or so around 19-20 y/o).

Recently (about a week now) I’ve had an odd reddish circle on the inside of my cheek, and it is not painful. At first I thought I had bit my cheek in my sleep, but now I am unsure.

It started out relatively flat, maybe even a little below the rest of my cheek. However, now it is puffy and raised.

I don’t know what it could be, any thoughts?

It's hard to determine. The most likely are trauma and or autoimmune response. Did you use any new toothpaste, rinses, herbal supplements, medications, cinnamon products, or similar agents? The lesion should resolve on its own unless you are using something to cause the autoimmune response.

Hey, I’m checking back in. So after 2 months of this thing growing, getting better, then coming back in a weird cycle I went ahead and had it biopsied. I should receive the results this upcoming week. Here is an updated image (post biopsy).
