What Is a Fever Blister?
5. Symptoms
To begin with, the patient is likely to feel an itching or tingling sensation for around a day before small spots appear on the lips. These spots will then develop into blisters and they will usually be found on the edges of the lips. Smaller blisters may sometimes merge together, and the blisters will eventually burst, oozing pus. Crusts are then likely to form.
In children, the sores will also sometimes be located inside the mouth. People who are experiencing the symptoms for the first time may also have painful gums and aches and pains in their muscles. A fever is another potential symptom, as is a headache and a sore throat. The patient may also develop swollen lymph nodes.
