Angular cheilitis?: A sore exactly in the corner of the mouth could be oral herpes (cold sore), but more likely is angular cheilitis, a different problem. It's often due to a superficial yeast infection, and antifungal creams may help. Neosporin probably won't help much. See your doctor and take it from there. Good luck! ...Read more
