Blisters in the throat?

Hello Dr.
Zheng, for the past 2-3 months, I have frequently felt a sensation of a foreign body in my throat after meals.
When I look in the mirror, I notice a small blister on the left side of my throat.
The blister appears and usually disappears on its own within about a day, but it occurs quite frequently—sometimes every 1-2 days and other times every 1-2 weeks.
The location of the blister varies but is always near the left side of my throat.
Could you please tell me what these symptoms might indicate and how I can improve this condition? I would be very grateful for your guidance.

Hello: The small blister may be a tonsillar cyst.
If it does not continue to grow or cause pain, you can start by drinking more water and self-monitoring.
If there are symptoms of gastroesophageal reflux, dietary modifications should be made, such as reducing coffee, tea, and dessert intake.
If you are concerned, you can visit an otolaryngology clinic for confirmation.
Wishing you peace and good health.
Sincerely, Dr.

More Info

Hello! Thank you for your question regarding recurrent throat blisters. Based on your description, it seems you are experiencing small fluid-filled blisters in your throat, particularly on the left side, which appear intermittently after meals. This condition can be quite uncomfortable and concerning, so let’s delve into the potential causes and solutions.

Possible Causes
1. Viral Infections: One of the most common causes of recurrent throat blisters is viral infections, such as herpes simplex virus (HSV). These blisters can appear in the throat and are often accompanied by other symptoms like sore throat, fever, or swollen lymph nodes.

2. Irritation or Trauma: If you are consuming hot, spicy, or acidic foods, they can irritate the sensitive mucous membranes in your throat, leading to the formation of blisters. Additionally, if you have a habit of clearing your throat frequently or coughing, this can also cause irritation.

3. Allergic Reactions: Allergies to certain foods or environmental factors can lead to inflammation and blistering in the throat. If you notice that the blisters coincide with specific foods or allergens, this could be a contributing factor.

4. Gastroesophageal Reflux Disease (GERD): Acid reflux can cause irritation in the throat, leading to the formation of blisters. If you experience heartburn or regurgitation along with the throat blisters, this might be worth investigating further.

5. Autoimmune Conditions: Conditions like Behçet's disease or other autoimmune disorders can cause recurrent oral and throat ulcers or blisters. If you have other systemic symptoms, it may be worth discussing this with your healthcare provider.

Recommendations for Management
1. Consultation with a Specialist: Given the recurrent nature of your symptoms, it would be beneficial to consult an Ear, Nose, and Throat (ENT) specialist. They can perform a thorough examination and may recommend tests to determine the underlying cause.

2. Avoid Irritants: Pay attention to your diet and try to avoid foods that may irritate your throat. This includes spicy, acidic, or very hot foods. Staying hydrated and consuming soothing liquids like warm teas may help alleviate discomfort.

3. Maintain Oral Hygiene: Good oral hygiene can help prevent infections that may lead to blister formation. Regular brushing and rinsing with salt water can be beneficial.

4. Manage Allergies: If allergies are suspected, consider using antihistamines or other allergy medications as advised by your healthcare provider. Identifying and avoiding allergens can also help reduce symptoms.

5. Monitor Symptoms: Keep a diary of your symptoms, noting when the blisters appear, any associated foods, and other symptoms. This information can be helpful for your healthcare provider in diagnosing the issue.

6. Consider Lifestyle Changes: If GERD is a concern, lifestyle modifications such as avoiding late meals, elevating the head while sleeping, and reducing fatty or spicy foods may help.

In conclusion, while recurrent throat blisters can be caused by various factors, identifying the underlying cause is crucial for effective management. Consulting with a healthcare professional will provide you with tailored advice and treatment options. I hope this information helps you find relief and answers to your symptoms. Wishing you good health!
