Red and Swollen Tongue: Causes and Remedies - Otolaryngology

I apologize, but I noticed that my tongue is red and swollen?


Hello doctor, I noticed a white, blister-like bump on the surface of my tongue yesterday, along with some raised red spots.
It hurts, and I feel very dry in my mouth, needing to drink water constantly.
I've been experiencing a disrupted day-night cycle lately, and I performed oral sex on my boyfriend the day before yesterday, so I'm not sure what might be going on...

Hello, the most common issue is glossitis, and the raised red spots may be inflamed taste buds.
It is advisable to drink plenty of water.
If the symptoms persist for a week without improvement, you should visit a clinic for an examination to check for any abnormalities.
Wishing you safety and good health.
Sincerely, Dr.
Cheng Jue-Yi, Head of the Department of Otolaryngology, Taoyuan Hospital, Ministry of Health and Welfare.

A: Hello! Thank you for reaching out with your concerns about your tongue. Based on your description, it sounds like you may be experiencing a condition known as "glossitis," which is inflammation of the tongue. The presence of a white bump and red spots can indicate a few potential causes, including infections, allergic reactions, or irritations.

1. Possible Causes:
- Infections: Viral infections, such as herpes simplex virus, can lead to painful sores on the tongue. Fungal infections, like oral thrush (caused by Candida), can also present as white patches on the tongue.

- Allergic Reactions: Sometimes, certain foods, medications, or oral hygiene products can cause allergic reactions, leading to swelling and discomfort.

- Irritation: Physical irritation from hot foods, spicy foods, or even trauma from biting your tongue can cause localized swelling and pain.

- Dehydration: You mentioned feeling dry in your mouth, which could be a sign of dehydration. This can exacerbate discomfort in the oral cavity and lead to a dry, swollen tongue.

2. Remedies and Treatments:
- Hydration: Ensure you are drinking plenty of water to stay hydrated, especially if you have been experiencing changes in your sleep schedule. Dehydration can worsen symptoms.

- Oral Hygiene: Maintain good oral hygiene by brushing your teeth and tongue gently and using an alcohol-free mouthwash to help reduce bacteria in your mouth.

- Avoid Irritants: Steer clear of spicy, acidic, or very hot foods that might further irritate your tongue. If you suspect an allergic reaction, try to identify and avoid the trigger.

- Topical Treatments: Over-the-counter topical anesthetics can help numb the pain temporarily. If you suspect a fungal infection, an antifungal mouth rinse may be beneficial, but it's best to consult a healthcare provider for appropriate treatment.

- Consult a Healthcare Provider: If the symptoms persist for more than a few days, worsen, or if you develop additional symptoms (such as fever, difficulty swallowing, or widespread rash), it is crucial to seek medical attention. A healthcare provider can perform a thorough examination and may recommend specific treatments based on the underlying cause.

3. When to Seek Help:
- If the pain is severe or if you notice any swelling that makes it difficult to breathe or swallow, seek immediate medical attention.

- If you have a history of sexually transmitted infections (STIs) or if you suspect that your symptoms may be related to a recent sexual encounter, it’s important to get tested and discuss your symptoms with a healthcare provider.

In summary, while there are several potential causes for the symptoms you are experiencing, maintaining hydration, practicing good oral hygiene, and avoiding irritants can help alleviate discomfort. However, if symptoms persist or worsen, please consult a healthcare professional for a proper diagnosis and treatment plan. Take care!
