crack at the corner of the mouth - B12 deficient?

delaluna

Has anyone ever got it? A slight crack at the corner edge of your mouth. What could be the cause of it? I looked up the internet and the possibility could be zinc or B12 deficiency. I'm a bit worried.

Thanks for your advice!

I do drool but I don't think this was the cause of it. Thanks though!
