Little bumps on lips

I recently have had chapped lips that crack.  Recently I would peel the dead chapped lip skin that flaps, off with my teeth due to stress.  A couple days after doing this, I noticed I began getting little bumps on my lip.  The bumps are on the inner part of the lip.  Still technically the lip, where lipgloss can be applied, but on the inner lining of the lip.  The bumps aren't white or itchy or burn, they are just obnoxious. Does anyone have any idea of what this might be?  I am thinking that it is just from peeling/ripping (stupid stupid idea) off the flappy parts of my chapped lip, and the lip area being irritated due to the ripping of the skin as well as lipgloss applied afterwards.
