This started as a very slightly coarse spot inside my cheek. I could feel it with my tongue, but could only visualize the porous caracteristic of the skin on reflex. This was three months ago.
This is how it looks like now:
Clearly more visible. A little bit red. It has also created some kind of salience which is easiy detected just with my tongue sitting normally on my mouth. The area is a bit sensitive too.
What is this?
