Canker Sores are non-cancerous mouth ulcers that can cause great discomfort. Appearing in simple and complex types, these sores can painfully affect all mouth activity and make a chore out of speaking, chewing or sipping. They can appear in any fleshy area of the mouth, including the tongue, gums, inner lips and cheeks. They tend to be preceded by a tingling feeling or mild burning sensation in the area. They can be identified by their telltale round shape and their white/grey coloring often edged with red. Symptoms also include fever, an overall sluggish feeling and inflamed lymph nodes. Canker sores can grow to uncomfortably large sizes, can spread and may sometimes last more than a fortnight.
