What could be the cause of a blister in my mouth?
I am a 22-year-old female. I have a blister in my mouth on the right anterior pillar. It hurts to swallow. What could be the cause of this? I have no other symptoms and I have never had this happen before. I woke up three days ago with pain in my throat. I assumed it was a sore throat but I noticed that it hurt near the back of my mouth instead of the actual throat. I have not done anything to treat the pain except eat a tablespoon of honey before going to sleep.
@madhar22 The most common causes of blisters in the mouth are canker sores. Canker sores also called aphthous ulcers, are small, shallow lesions that develop on the soft tissues in your mouth or at the base of your gums. Unlike cold sores, canker sores don't occur on the surface of your lips and they aren't contagious. They can be painful, however, and can make eating and talking difficult. Canker sores are usually secondary to viral illnesses such as a flu virus or cold. Canker sores are not infectious. canker sores usually resolve within two weeks. To increase healing, you can rinse your mouth with salt water. If your symptoms do not improve or worsen, you should seek medical attention.
