Look For These Signs Of A Canker Sore
Difficulty Talking Or Eating

For some individuals, the pain of their canker sore, particularly when it progresses beyond the initial tingling and burning sensations, may prevent them from eating or drinking. It often occurs because the area is inflamed, so elements like pressure or texture can aggravate the inflammation. Spicy and salty foods are the two most popular triggers for additional pain and are the hardest to consume, so try to avoid these foods when affected by a canker sore. While it may be painful, it is important to eat and drink like normal, so your body can have the nutrients and hydration required to heal the canker sore. Turn to softer foods and bland choices, in the beginning, to avoid unnecessarily aggravating the canker sore. Work to figure out what foods you can tolerate without much pain and stick to those. Smoothies (without acidic fruits) can be wonderful for getting lots of nutrients.

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.
