Then one night before bed, I noticed a small bump appearing on the inside of my lip
. By the next day, I woke up to the bottom of my lip
being swollen, I went to the doctor and they told me it was a canker sore because at this time the bump was completely inside my lip (around the line where you would naturally tear your lips with your teeth). As the day progressed, the bump started to grow, swell and contain a yellow center. Eventually, this bump caused a small bump, directly on top of it!
