An aphthous ulcer or canker sore is a type of mouth ulcer which presents as a painful open sore inside the mouth caused by a break in the mucous membrane. The condition is also called aphthous stomatitis, especially if there are multiple or recurring mouth ulcers.
The term aphtha means ulcer; It has been used for many years to describe areas of ulceration on mucous membranes. Aphthous stomatitis is a condition which is characterized by recurrent discrete areas of ulceration which are almost always painful. Recurrent aphthous stomatitis (RAS) can be distinguished from other diseases with similar appearing oral lesions, such as certain viral exanthems, by their tendency to recur, their multiplicity, and chronicity. Recurrent aphthous stomatitis is one of the most common oral conditions. At least 10% of the population suffers from it. Women are more often affected than men. About 30-40% of patients with recurrent aphthae report a family history
The exact cause of aphthous ulcers is unknown. In some cases they are thought to be caused by an overreaction by the body's own immune system. Factors that appear to provoke them include stress, fatigue, illness, injury from accidental biting, hormonal changes, menstruation, sudden weight loss, food allergies, and deficiencies in vitamin B12, iron, and folic acid. Some drugs, such as nicorandil, have been linked with mouth ulcers. A well known cause for ulcers in the mouth is when the skin inside the mouth is opened up, a common cause of this is biting one's lip or any tissue within the mouth.

I got diagnosed with herpes simplex virus (type 2) about 4 years ago, whilst I was still attending college and had a mindless one-night stand. I understand loads of people say this, but I swear I had never done that sort of thing before. I just made a mistake that one time and all of a sudden it seemed like I was going to have to live with the consequences for my entire life. The hardest part was feeling I could never date other men again. In the end, who wants to go out with someone that has sores around her private parts? But since a friend shared this movie https://tr.im/fsGOt everything got better.
Not only was I able to clear away all traces of the hsv from my body in less than 21 days, but I was also able to begin dating again. I even met the man of my dreams and I'm so lucky to write that just a week ago, in front of everybody in a busy restaurant, he got down on one knee and proposed to me!! This program provided the opportunity to be happy and experience real love again. Now I hope that I can help others too by sharing this story.

No, it is not herpes. It's a virus and there are many theories about the causes, but nothing has been proved. Read about cankers on the Internet. There are lots of sites.
