For 2 months I have suffered with dry cracked lips, redness in corners of mouth. Moisture tends to collect in corners of mouth. I feel like if I smile my mouth is stretching. I am constantally wiping the moisture out of the corners of my mouth. My lips have a burning sensation inside and out. Mouthwash sets me on fire, but just the anterior portion of my mouth. I have tried many kinds of chapstick. The redness in the corners of my mouth is spreading. It is very embarassing. I thought maybe it was a yeast infection,but i used nystation oral suspension and took 2 diflucan, one week apart without relief. PLEASE HELP.
