Canker sores are gray or white sores surrounded by a red inflamed area.old sores typically result from a viral infection called herpes simplex virus (HSV). Cold sore blisters can occur on many different parts of the body but are most common on or around the lips, cheeks, or nose and also (on rare occasions) in the eye.
Vitamin deficiencies, specifically vitamin B12, foliate (folic acid), and iron, may trigger canker sore development. Hormonal changes, notably during menstruation, pregnancy, and menopause, have been linked to canker sores. Canker sores often run in families. Genetics may be a factor for many canker sore sufferers.
