Both fever blisters and canker sores can have triggers that produce flare-ups. Try to identify and avoid triggers so your flare-ups become less frequent.
- Sun exposure may sometimes trigger outbreaks of fever blisters. If you have recurring blisters, using sunscreen may help reduce their frequency.
- Fever blisters are contagious. Avoid kissing, sharing eating utensils, cups, water bottles, or other items if you are experiencing symptoms.
- Be aware that in young children, fever blisters can cause loss of appetite, drooling, and fever that can last for several days.
- Talk to your doctor or your child’s pediatrician if symptoms are severe or recur frequently.
- If you regularly get canker sores, talk to your doctor about testing for food allergies, as allergic reactions can sometimes trigger sore canker outbreaks.
