Hope everything is OK brother, Im sure it will be. I had a couple of lumps on the inside of my cheeks recently, was driving myself crazy, worrying.
Turned out they are a build up of scar tissue from bad cheek biting, most likely when Im asleep.
Just shows you lumps & bumps are more often than not nothing serious but always good to get things checked out.
In future please specify which cheeks you're referring to as this can cause great confusion, and indeed worry, to your reader.
I guess Theymos was worried that people might actually start to understand the existing trust system. Wouldn't want that to happen.
