The outside corner of my mouth has a large crack running across it--what is this?

Question

I can't seem to heal it--every once in a while this happens--and I don't know what to put on it to make it heal. What can I do and why does this keep happening? I've been putting vaseline on it, but nothing.

Answer 1

i also have one on my left side, mine is here for over a month now and doesnt want to heal.....

have you ever had a complete blood count? maybe you can have an iron deficiency, cause i have anemia and thats one symptom.  

Answer 2

That is Angular Cheilitis. Check out this link for the pictures. Most likely you are not having enough iron or vitamin b.

You need Riboflavin-VitB2-found in Multivitamin tablets or Metatone Tonic(liquid)
