Your Symptoms:
• Right tonsil bigger than left for 2 years.
• Right external ear canal swelling without pain, but with tightness sometimes.
• Mild itching and needle-like pain in throat/tonsil.
• Feeling of tightness in ear.
• No severe pain or systemic symptoms.
First, to answer you honestly:
• Tonsil asymmetry is not always normal, especially when it persists over years.
• But it is not always serious either.
• Most cases are due to chronic inflammation, scarring, or benign conditions.
• Rarely, it can be a sign of something concerning like a slow-growing tumor (example: lymphoma, tonsillar cancer).
Important Red Flags you should watch for (if any are present, it’s more serious):
• Rapidly increasing tonsil size.
• Weight loss.
• Difficulty swallowing (progressive).
• Ear pain severe and deep inside.
• Blood in saliva.
• Lump in neck (hard, not painful).
• Severe trismus (difficulty opening mouth).
That’s why doctors recommend physical check-up.
Summary:
• Most likely: Chronic tonsillitis, chronic mild otitis externa.
• But to be safe, one ENT visit (for physical exam + maybe fiberoptic check) is recommended.
• Probably not serious, but needs ruling out serious causes properly once
Next Steps
You have mostly mild symptoms without strong red flags.
But, because tonsillar asymmetry persisting >1 year is considered important to assess properly, I recommend getting examined physically by an ENT surgeon.
If an in-person clinical examination is not possible — it is advisable to undergo a Contrast-Enhanced CT (CECT) scan of the neck (extending from the base of skull to the clavicle).
