I just begun to see these grooves show up on my lips. They are showing up more now because of this treatment. I have a whole folder of pictures of my lips in the Image Gallery named after my screen name.
I sure don't want to go back to that stage of EC again. A candidal or staph infection of the mucosa that creates a biofilm inside the mucosa seems to be the most logical explanation of one type of EC because the excessive brushing & mouthwash rinsing has definitely helped my condition to improve.
