How to diagnose and treat canker sores?

A canker sore that appears in the mouth or throat. Mouth ulcers are also known as aphthous ulcers and mouth ulcers. Canker sores usually appear on the cheeks or inside the lips but can sometimes affect the back of the throat and the tonsils.

The sores usually heal by themselves and are not contagious. Over-the-counter (OTC) medications and home remedies can ease symptoms and help recover.

What are the symptoms of Canker sores?

Canker sores in the tonsils can be excruciating, causing a sore throat on one side. Some people confuse it with strep throat or tonsillitis. It depends on where the pain is; if you look at the back of your throat, you can see it. It will usually look like a minor wound.

You may also feel a

burning sensation in the area for a day or two before the pain subsides. When your throat is sore, you may feel itchy when eating or drinking something acidic.

What causes canker sores?

No one is sure about the exact cause of canker sores.

But some things can cause or increase the risk of developing it in some people, including:

  • Food allergies to acidic or spicy foods, coffee, chocolate, eggs, strawberries, nuts, and cheese
  • emotional pressure
  • smallmouth ulcers, such as dental work or biting on the cheek
  • Mouthwash and toothpaste that contains sodium lauryl sulfate.
  • virus infection
  • certain bacteria in the mouth
  • Hormonal changes during menstruation
  • Helicobacter pylori (H. pylori), the same bacterium that causes peptic ulcers
  • Malnutrition, including iron, zinc, folic acid, or vitamin B12 deficiencies

Certain medical conditions can also cause canker sores, including:

  • celiac disease
  • Inflammatory bowel diseases (IBD), such as ulcerative colitis and Crohn’s disease
  • Behcet’s disease
  • HIV and AIDS

Although fistula can affect anyone, it is more common in adults and adolescents, and it is more common in women than in men. Family history also plays a role in why some people often get canker sores.

Treatments and home remedies

Canker sores usually heal on their own. However, some treatments and medications can help ease the pain.

Home remedies

People can gargle with salt water by dissolving half a teaspoon of salt in a cup of warm water. These can be used to wash the throat and tonsils up to three times a day.

Drinking ice water or drinking ice cubes can reduce the pain a little. Eating yogurt or frozen soft ice cream may also help. It is best not to eat anything with sharp edges to prevent further fistula development.

If a person suffers from recurrent canker sores, the following lifestyle changes may be beneficial:

  • Avoid acidic or acidic foods.
  • reducing stress
  • Take an iron or vitamin B supplement.

medical treatment

Medications can reduce pain and inflammation, which can help speed up the healing of mouth sores. People can find anti-inflammatory gels and creams that contain anti-inflammatory or pain relievers and are applied directly to the wound. Some gels cover the wound with a protective barrier that prevents further itching.

Treating a sore throat can be difficult. Mouthwash may be the most effective way to reduce pain, inflammation, and the risk of infection. Antiseptic or antimicrobial mouthwash may be best. Various insecticides are available for purchase online. Anyone unsure what to try can talk to a pharmacist or doctor before buying medicine to treat canker sores.

For severe fistula injuries, a person may need a prescription. The pills can reduce inflammation and help treat severe wounds. Low-level laser treatment may help with acute or recurrent canker sores. Although it is not a cure, it can dry out wounds and speed up the healing process if they do not heal.

causes and risk factors

It is unclear why some people are more likely to develop canker sores than others. However, there may be a genetic link, as mouth ulcers tend to run in families.

  • Some possible causes of mouth ulcers are:
  • stress and hormonal changes
  • mouth and throat ulcers
  • iron or vitamin B deficiency
  • spicy or acidic foods

People with weakened immune systems are at greater risk of developing injuries and it can include people with HIV, leukemia, or rheumatoid arthritis. Short-term immunity may increase the risk of mouth ulcers in the short term. This reduction can occur after an illness, during pregnancy, or with specific medical treatments such as chemotherapy.

Certain primary medical conditions can increase your risk of developing canker sores. These include inflammatory bowel diseases such as Behcet’s disease and ulcerative colitis.

How long do canker sores last?

Canker sores (aphthous ulcers) from inside your mouth or brain. Although they are painful and make it difficult to speak or eat, they usually do not cause permanent damage. Most mouth ulcers get better on their own within a few weeks.

Many home remedies can help speed up the healing process, but it is not a cure-all. There is no single treatment possible to cure fistula overnight. Most home remedies for canker sores have not been well studied, so use them cautiously. If you have any questions, you can contact your doctor’s office.

Canker sores vs. cold sores

Canker sores and cold sores are small, painful ones that itch or cause itching. However, Canker sores appear inside the mouth while cold sores appear outside, usually around the lips.

The hippocampal virus causes colds. It spreads through close contacts, such as kissing or sharing a drink, and canker sores are not contagious.


Canker sores can be more complex than a sore throat. If applying a cream or gel directly to the wound is difficult, a pharmaceutically formulated mouthwash may help.

They can recur in people with intestinal ulcers. Avoiding foods that can irritate the throat and reducing stress can help reduce recurrences. It is best to see a doctor if the small wound does not heal within two weeks.
