I've had this one bump beside my lip for almost a month now. This is the first time I got it. The bump used to be bigger. I tried popping it once (only blood came out) then it became smaller (current size). It doesn't hurt even if i press on it, nor fluctuates in size, nor itches, it's just there. I also tried putting on epiduo on it just to make sure if it's a pimple, but it didnt make a difference. Also, it doesn't seem like pus is inside because the fluid in it is clear-colour (i.e. not yellowish/brownish). I have no idea what this is...
If it helps, i remove the hairs around my lips by plucking.
