The area between my upper and lower lips is irritated on both sides. Kind of chapped and red (mild) and very persistent. It can crack when I open my mouth.

lip balms didn't seem to help much. Been going on for about a month now.

This happened just after I went on a course of antibiotics for a sinus infection, and I suspect I may have some yeast overgrowth or something...

Has anyone had this? Better yet, has anyone found a way to alleviate the symptoms without having to run to the doctor? I put some monostat on it last night, thinking that if it were candida-related...
