What causes white spots in the throat accompanied by a foreign body sensation?

In general, the sensation of having white spots and a foreign body in the throat may be caused by pharyngeal keratosis, stomatitis, chronic cryptic tonsillitis, acute pharyngitis, or sinusitis. A detailed analysis is as follows:

1. Pharyngeal Keratosis

Pharyngeal keratosis typically occurs in the epithelial layer of the palatine tonsil crypts or between the follicles of the lingual tonsils. Clinically, it presents with a honeycomb-like appearance, with small white granules visible at the crypt openings and in the throat area. Common symptoms include dryness, thirst, and a sensation of a foreign body. Patients may follow medical advice to take medications such as Penicillin V potassium tablets or Amoxicillin dispersible tablets to relieve symptoms.

2. Stomatitis

Stomatitis refers to inflammation of the mucous membranes in the oral cavity and throat. It can be caused by various factors, including bacterial or viral infections, allergies, or trauma. The presence of white spots and a foreign body sensation in the throat may be among the symptoms of this inflammation. Under medical guidance, patients may use medications such as Cefixime tablets or Acyclovir tablets for treatment.

3. Chronic Cryptic Tonsillitis

This condition involves evident chronic inflammation in the tonsillar crypts and lymphoid follicles. Large amounts of desquamated epithelium, bacteria, lymphocytes, and white blood cells accumulate within the crypts, forming pus-filled plugs that significantly enlarge the crypts, sometimes resulting in small cysts or abscesses. These appear as tiny white grain-like particles located on both sides of the pharynx, causing a sensation of a foreign body. Patients may follow medical advice to take medications such as Clindamycin hydrochloride tablets or Roxithromycin capsules to alleviate symptoms.

4. Acute Pharyngitis

Acute pharyngitis is an acute inflammation of the pharyngeal mucosa, submucosal tissues, and lymphoid tissue, which may cause a sensation of a foreign body during swallowing. After onset, the mucosa becomes congested and edematous; when the submucosal glands become inflamed and obstructed, white granular secretions may form. As these secretions are expelled, they leave behind honeycomb-shaped glandular cysts. Under medical guidance, patients may use medications such as Azithromycin capsules or Roxithromycin capsules for treatment.

5. Sinusitis

Sinusitis is a chronic inflammation of the sinuses. It may cause postnasal drip—secretions flowing down the back of the throat—forming white spots or cloudy substances in the throat. These spots and the sensation of a foreign body are related to nasal and pharyngeal secretions. Patients may follow medical advice to take medications such as Cefalexin dry suspension or Clindamycin hydrochloride tablets for treatment.

In summary, if a patient's discomfort continues to worsen, prompt medical attention is recommended to prevent serious complications.
