Persistent Phlegm and Sore Throat: Possible Causes and Solutions

Persistent phlegm in the throat?

Hello, doctor.
In mid-June of this year, I had a cold and visited a doctor for medication.
Later on, I felt much better, but every morning when I wake up, I feel like I have phlegm that I can't cough out.
I need to use a bit of a gag reflex to expel it, and when I do, there are some blood streaks in it.
Two days ago, I woke up with a sore throat, my body feels achy, and my neck feels swollen.
I checked my neck and there are no lumps, but pressing firmly below my ears causes some pain.
I don't have a runny nose, but I do have nasal congestion.
Will drinking more water and resting help? Do I need to undergo any tests?
Additionally, I have another question.
I'm not sure if this is related to my wisdom tooth extraction.
I had my upper right wisdom tooth removed in the second half of last year, and the doctor mentioned that this tooth is close to the nasal area (I'm not sure how to refer to it).
He warned that if not done properly, I might choke when drinking water.
The extraction went smoothly, but I have a concern: when I inhale, it feels like air is flowing in my mouth, and my sense of smell isn't as good as it used to be.
Could these two issues be related? Thank you, doctor.

More Info

Persistent phlegm and a sore throat can be quite bothersome and may stem from various underlying causes. Based on your description, it seems that you have been experiencing these symptoms following a cold, which can often lead to post-nasal drip, where mucus accumulates in the throat, causing irritation and discomfort. Here are some potential causes and solutions to consider:

Possible Causes
1. Post-Nasal Drip: After a cold, the nasal passages can produce excess mucus, which drips down the back of the throat, leading to irritation and a sore throat. This can also cause a sensation of phlegm that is difficult to expel.

2. Allergies: Allergic reactions can lead to increased mucus production and throat irritation. Common allergens include pollen, dust mites, and pet dander.

3. Infection: A lingering viral infection or a secondary bacterial infection could be responsible for your symptoms. Conditions like sinusitis or pharyngitis can cause sore throats and phlegm production.

4. Gastroesophageal Reflux Disease (GERD): Acid reflux can irritate the throat and lead to the sensation of mucus accumulation. This may explain the need to cough or clear your throat frequently.

5. Dental Issues: Since you mentioned having your wisdom tooth extracted, it is possible that there could be a connection. If the extraction site became infected or if there was damage to nearby structures, it could lead to referred pain or altered sensations in the throat and nasal passages.

Recommended Solutions
1. Hydration: Continue to drink plenty of fluids. Staying hydrated helps thin mucus, making it easier to expel. Warm liquids, such as herbal teas or broths, can be soothing for a sore throat.

2. Steam Inhalation: Inhaling steam can help moisten the airways and loosen mucus. You can do this by taking a hot shower or using a bowl of hot water with a towel over your head.

3. Saltwater Gargle: Gargling with warm salt water can help soothe a sore throat and reduce inflammation.

4. Over-the-Counter Medications: Consider using over-the-counter antihistamines if allergies are suspected, or throat lozenges to soothe irritation. Decongestants may also help if nasal congestion is present.

5. Consult a Doctor: Given the presence of blood in your phlegm, it is crucial to consult a healthcare professional. Blood-streaked mucus can indicate a more serious condition, such as an infection or irritation in the throat or lungs. A doctor may recommend a throat culture, chest X-ray, or other diagnostic tests to determine the underlying cause.

6. Dental Follow-Up: Since you mentioned the extraction of your wisdom tooth, it may be beneficial to follow up with your dentist. They can check for any complications related to the extraction, such as dry socket or infection, which could contribute to your symptoms.

Conclusion
In summary, your symptoms may be related to post-nasal drip following a cold, allergies, or even complications from your dental procedure. It is essential to monitor your symptoms closely and seek medical attention, especially due to the presence of blood in your phlegm. A healthcare provider can perform the necessary examinations and tests to provide a definitive diagnosis and appropriate treatment plan. In the meantime, maintaining hydration and using home remedies can help alleviate some discomfort.
