What Causes A Sore Throat
Most sore throats are caused by viruses, such as the cold or flu virus. Some of the more serious causes of sore throat include tonsillitis, strep throat, and mononucleosis . Other causes include smoking, mouth breathing at night while you sleep, pollution, and allergies to pets, pollens and molds. General anesthesia during surgery can cause a sore throat.

Red Bumps Or Spots On Back Of Throat: What It Means And How To Get Rid Of It
Jenny Hills, Nutritionist and Medical Writer Health
Red bumps on the back of your throat usually mean that you have an inflammation, irritation, or an infection in your upper respiratory tract. Because the back of the throat is already red, it can be difficult to notice red spots on your throat. The red bumps can appear as small red dots in the throat or they can look like sore red ulcers. Usually, treating red spots on your tonsils or throat involves soothing the irritation or gargling with salt water to kill off infection-causing germs.
Very often, red bumps on your throat and tonsils are accompanied by other symptoms. For example, a sore throat caused by a viral infection can cause red bumps as well as coughing, phlegm, or sinusitis. You may also notice white bumps on the back of your throat or have swollen glands in your neck.
Usually, red spots on the back of your throat go away using home remedies to treat the discomfort. In some cases, you may need to see your doctor because infections causing red throat bumps can spread deeper into your respiratory tract.

How Might A Doctor Treat Throat Ulcers
Healthcare professionals will use different medical treatments to address the underlying cause of your throat ulcers.
Treatment may involve changing a medication you are taking. However, do not change any of your medications without first consulting your doctor.
A clinician may also recommend taking a medication that numbs the ulcer. Some alcohol-free mouthwashes can also help relieve pain. This is also the case if the ulcer is present due to a condition such as Behçets syndrome.
If the throat ulcer is the result of an infection, your doctor may recommend:
- acetaminophen if a fever is present
- oral pain relievers, including lozenges
- a bland diet, such as cold milk and ice cream
Antibiotics will not work if the infection is viral, as in the case of herpangina.
Anti-yeast medications can help relieve throat ulcers that may have worsened due to a yeast infection.
Silver Nitrate Canker Sores Treatment

Silver nitrate is a natural chemical compound thats been used since the 13th century for its antimicrobial properties. As soon as silver nitrate is activated by contact with moisture, it delivers free silver ions to wounded tissue. This reaction binds the tissue and obstructs blood vessels, which cauterizes active wounds and reduces the pain they cause.
Overall, research shows that treating canker sores with silver nitrate is a simple and affordable way to decrease the pain caused by ulcers, though the healing time remains about the same.

Can Canker Sores Really Appear On The Tonsils
When canker sores develop on the tonsils or in the back of the throat, they display distinct red edges and a yellow, gray, or white center. The pain caused by a canker sore in the throat is so severe that its often mistaken for strep throat or tonsillitis.
Not sure if your sore throat is the result of a canker sore, allergies, or something else entirely? Try examining your throat and tonsils with a mirror and a flashlight. If a canker sore is present, itll look like a small, single sore.
Throat Ulcers And Covid
Certain viral infections can increase the risk of throat ulcers. The SARS-COV-2 virus that causes COVID-19 may increase the risk of throat and mouth ulcers, though these are not common symptoms of the disease.
Most case studies reporting a connection between COVID-19 and ulcers refer to ulceration and blistering of the mouth. For example, a 2020 case series reports one case of mouth ulcers in a person with confirmed COVID-19 and two cases in people with suspected COVID-19.
It is still unclear whether COVID-19 directly causes throat and mouth ulcers or whether it makes a person more susceptible to secondary infections that can cause these types of ulcers.
Anyone who experiences symptoms of a throat ulcer should see their doctor. The symptoms of a mouth ulcer may mimic those of other, more serious conditions, so it is important to receive an accurate diagnosis.
Symptoms that warrant a visit to the doctor include:
- pain that does not respond to OTC medication
- inability to eat or drink
- sores lasting for more than a few days
- symptoms of GERD that do not respond to OTC medication
In some cases, a throat ulcer may be a symptom of a serious underlying medical condition. Anyone experiencing the following symptoms should seek immediate medical attention:
