Canker sores are a common form of mouth ulcer. They occur in women more often than men. They may occur at any age, but usually first appear between the ages of 10 and 40.
Canker sores usually appear on the inner surface of the cheeks and lips, tongue, soft palate, and the base of the gums.
They usually begin with a tingling or burning sensation, followed by a red spot or bump that ulcerates. Pain decreases in 7 to 10 days, with complete healing in 1 to 3 weeks. Particularly large ulcers (greater than 1 cm in diameter) often take longer to heal (2 to 4 weeks). Occasionally, a severe occurrence may be accompanied by nonspecific symptoms of illness, such as fever or malaise. Canker sores often come back again in the future.
There may be an inherited tendency to develop canker sores, as they often run in families. There may also be an immune system link. Ulcers may develop in response to a mouth injury such as dental procedures or aggressive tooth cleaning.
Canker sores may also occur at the site of a bite when the tongue or cheek is bitten. They can be triggered by emotional stress, dietary deficiencies (especially iron, folic acid, or Vitamin B-12), menstrual periods, hormonal changes, food allergies, and similar situations. They occur most commonly with viral infections. They may occur with no identifiable cause.
Symptoms Return to top
A burning or tingling sensation before other symptoms develop (warning symptom)
Skin lesion on mucous membranes of the mouth
Begins as a red spot or bump
Then develops into an open ulcer
Usually small, 1-2 mm to 1 cm
Occasionally larger than 1 cm
Single or clusters, often appears in groups (crops)
Painful
Center appears white or yellow with fibrous texture
Halo border is bright red (a red halo may not always be present)
May have gray membrane just prior to healing
Less common symptoms, which may appear at the time of the canker but may or may not be related, include:
Fever
General discomfort or uneasiness (malaise)
Swollen lymph nodes
Signs and tests Return to top
A diagnosis is based on the distinctive appearance of the lesion. If canker sores persist or continue to return, a health care provider or dentist should be consulted to rule out other causes of mouth ulcers. (These include erythema multiforme, drug allergies, herpes infection, pemphigus, pemphigoid, bullous lichen planus, and other disorders.)
Squamous cell carcinoma may first appear as a mouth ulcer that does not heal, but this is rare. A relatively new ulcer-like condition is hairy leukoplakia, a condition that occurs with HIV infection and may be mistaken for the common canker.
A skin lesion biopsy may be used to differentiate a canker sore from other causes of mouth ulcers.

I got diagnosed with herpes (type 2) about five years ago, while I was still attending college and had a foolish one-night stand. I understand lots of young ladies will say this, but I swear I had never done that sort of thing before. I just made a huge mistake that one time and suddenly I felt like I was going to have to live with the consequences for my entire life. The hardest part was feeling I could never date men again. After all, who wants to go out with someone who has sores around her private parts? But since a friend shared this video https://tr.im/e2X1B everything got better.
Not only was I able to eliminate all traces of the herpes virus from my body in less than 3 weeks, but I was also able to begin dating once more. I even met the guy of my dreams and I'm so lucky to write that just last week, in front of everybody in a packed cafe, he got down on one knee and proposed to me! This program provided me the opportunity to be happy and experience real love. Now I want to help you too by sharing this with the World.

these are sores of the mouth also known as canker sores and their etiology or underlying cause is not fully understood. There are different levels of severity. I hope you feel better soon.
