OK i have never had an ulcer in my entire life. About 3-4 days ago the inside of my lower lip started to hurt like crazy. I looked and saw this white patch near the bottom of my lip near the point where it meets my gums. Of course being the hypocondriac that i am i looked up mouth cancer and now have myself freaked out. Has anyone else ever had any ulcers on their lip and how long does it take for them to leave, also is there anyway to heal them faster.
