Should I avoid activities when I have aphthous stomatitis (canker sore)?

If you have a canker sore, in most instances it will not affect your physical activity or other activities. Depending upon your normal diet, it may be necessary to alter some foods for a few days. Stay away from hot, spicy or acidic foods that can irritate the sore.

If you have aphthous stomatitis (a canker sore) or an ulcer on the inside of your mouth, you should try to avoid especially stressful activities, as stress often triggers these sores. Some ways to help relieve stress include meditation, yoga, deep breathing, or exercise.

Also, avoid spicy foods and products that may irritate your canker sore. Canker sores may be painful, but they are not contagious, and they normally go away on their own within a week or two. 

When you have aphthous stomatitis (canker sore), you can usually go about your daily activities as usual. A slight fever or feeling of being tired may limit physical activities that require exertion. Eating spicy foods or using strong mouthwash or toothpaste may irritate your mouth ulcers. Try to avoid stress because it can aggravate your condition.
