Throat issues


Hello Doctor, in the past two days, I have occasionally experienced symptoms of inflammation in my upper throat (there are no symptoms in the morning, but they may appear in the afternoon).
I always have phlegm in my throat that I cannot cough up.
A week ago, I visited a clinic due to a cold, and the doctor prescribed antibiotics for three days.
After finishing the medication, my symptoms disappeared, but in the past few days, the symptoms (inflammation in the upper throat and phlegm) have reappeared.
I would like to ask if this is pharyngitis? Thank you for taking the time to respond, Doctor.

More Info


Throat inflammation, commonly referred to as pharyngitis, can manifest with a variety of symptoms, including sore throat, difficulty swallowing, and the sensation of mucus or phlegm in the throat. Your description of experiencing symptoms that fluctuate throughout the day, particularly with the presence of phlegm that is difficult to expel, suggests that you may indeed be experiencing a form of throat inflammation.

Pharyngitis can be caused by several factors, including viral infections, bacterial infections, allergies, irritants, and even environmental factors. Given that you recently had a cold and were treated with antibiotics, it is important to consider the following:
1. Viral vs. Bacterial Infection: Most cases of throat inflammation are viral in nature, often caused by common viruses such as the rhinovirus or adenovirus. Antibiotics are effective against bacterial infections, such as streptococcal pharyngitis (strep throat), but they do not work against viruses. If your symptoms improved with antibiotics but then returned, it could indicate that the initial infection was viral, or that you may have developed a secondary bacterial infection.

2. Post-Nasal Drip: The sensation of phlegm in your throat could be related to post-nasal drip, which occurs when mucus accumulates in the nasal passages and drips down the back of the throat. This can be exacerbated by allergies, sinus infections, or even irritants in the environment. Post-nasal drip can lead to throat irritation and inflammation, contributing to your symptoms.

3. Environmental Irritants: Exposure to smoke, pollution, or dry air can irritate the throat and lead to inflammation. If you have been in an environment with such irritants, it may explain the recurrence of your symptoms.

4. Allergies: Allergic reactions can also cause throat inflammation and the production of mucus. If you have a history of allergies, consider whether you have been exposed to any allergens recently.

5. Chronic Conditions: Conditions such as gastroesophageal reflux disease (GERD) can cause throat irritation due to acid reflux. If you experience heartburn or regurgitation, this could be a contributing factor.

Given your symptoms and the recent history of a cold, it would be advisable to monitor your condition closely. If your symptoms persist or worsen, or if you develop additional symptoms such as fever, difficulty breathing, or severe pain, it would be prudent to seek further medical evaluation. A healthcare provider may perform a throat examination, consider a rapid strep test, or recommend additional treatments based on the underlying cause of your symptoms.

In the meantime, here are some self-care measures you can take to alleviate your symptoms:
- Stay Hydrated: Drink plenty of fluids to help thin mucus and soothe your throat.

- Gargle Salt Water: Gargling with warm salt water can help reduce inflammation and provide temporary relief.

- Use Humidifiers: Adding moisture to the air can help soothe a dry or irritated throat.

- Avoid Irritants: Stay away from smoke, strong odors, and other irritants that may exacerbate your symptoms.

- Over-the-Counter Medications: Consider using over-the-counter pain relievers or throat lozenges to help manage discomfort.

If you continue to experience symptoms or have concerns about your throat inflammation, it would be wise to consult with a healthcare professional for a thorough evaluation and tailored treatment plan.
