Look For These Signs Of A Canker Sore

Swollen Lymph Nodes

The inflammation from your canker sore can begin to cause swelling in your lymph nodes, mouth, tongue, or throat. If swollen lymph nodes are causing you severe discomfort or are making it challenging to breathe, it is important to seek immediate medical attention. Swollen lymph nodes that persist for an abnormal length of time can also be indicative of other health issues. It is important to monitor your canker sore and be on the lookout for any more severe symptoms that could arise from your condition. A sore that won't go away on its own after an extended period will require medical attention.
