Visit your doc: Angular cheilitis could be a multifactorial problem (your underlying condition, bacterial or fungal infection, vitamin deficiency (Vit B mostly)). Visit you PPC for a proper diagnosis and treatment.

Visit your MD: There are some conditions that will produce patients to have irritation at the corners of the mouth. Please visit your primary MD to achieve a proper diagnosis and treatment. Hope this helps.

See DDS: Need to visualize to comment. Possible angular chelitis or other differential diagnosis dependent on clinical examination- see dentist to initially diagnose.
