Hi, I am Dr. Atul kumar nimawat MS ENT. Unilateral tonsil enlargement persisting for over 2 years, especially when accompanied by occasional pain or pricking/needle-like sensations, should be carefully evaluated to rule out both benign and potentially serious conditions. Possible causes include: 1. Chronic Tonsillar Hypertrophy: Sometimes, one tonsil remains persistently enlarged due to repeated infections in the past. This asymmetry can remain stable for years without necessarily indicating active disease. 2. Tonsillar Cyst or Lymphoid Hyperplasia: Benign cysts or localized overgrowth of lymphoid tissue can cause long-standing, painless enlargement with intermittent discomfort. 3. Glossopharyngeal Neuralgia: Sharp, needle-like pain near the tonsillar area may result from nerve irritation, especially if the pain is episodic and triggered by swallowing or talking. 4. Dental or Orofacial Referred Pain: Sometimes, pain from nearby dental or jaw joint (TMJ) issues can be referred to the tonsillar region. 5. Post-Tonsillitis Fibrosis or Scarring: Scarring from past infections may cause asymmetrical tonsillar appearance or a sensation of tightness or prickling. 6. Tonsillar Neoplasm (to be ruled out): Although rare, persistent unilateral tonsillar enlargement especially if it is hard, irregular, or increasing in size.
