here is the situation. about 10 months ago, i started using a toothbrush that has a squarish shape close to the head of the brush. maybe 3 to 4 months after using the new toothbrush, i noticed that my bottom lip - toward the corner - gets swollen. the swelling is like an elongated, rounded and raised bump shape.
when i wake up in the morning, the swelling is not present. the lip looks perfectly normal with no sign of irritation or swelling. after i brush my teeth, the swelling is there but then goes down after 3 minutes or so. i also notice that sometimes it will swell after i start talking for a few minutes but then goes down after i stop talking. it appears to swell when there is more blood flowing to the lips, if that makes sense.
i did a little investigation to see how the toothbrush rests against my lip when i brush. it appears that the brush is digging into the lip and creating an ever so slight crease. i guess, after months of repeated creasing, the lip has been damaged and swells at the crease.
i thought it could be herpes but it isn't painful. it has never blistered and it comes and goes randomly throughout the day. this is just my common sense diagnosis. oh, it's been about a week since i have stopped using the toothbrush.
my question is can herpes just come and go daily like the situation i'm describing? is there any other condition that could be causing my problem.
thanks in advance.
