Experiencing a canker sore on your tonsil can be both painful and concerning. These small, shallow ulcers that develop in the soft tissues of the mouth can cause significant discomfort when they appear on the tonsils, affecting basic activities like eating, drinking, and swallowing. Understanding their causes, symptoms, and treatment options is crucial for managing this condition effectively.
While canker sores commonly occur on the tongue, cheeks, or lips, tonsil canker sores present unique challenges due to their location and the vital role tonsils play in our immune system. This comprehensive guide will help you identify, treat, and prevent these uncomfortable lesions.
Identifying a Canker Sore on Your Tonsil
A canker sore on the tonsil typically appears as a round or oval-shaped white or yellowish spot surrounded by redness. Unlike strep throat or tonsillitis, which usually affect both tonsils, canker sores often occur on just one side. The lesion is usually small, measuring between 2-10 millimeters in diameter.
