Understanding Cold Sores -- Symptoms

What Are the Symptoms of Cold Sores?

• Fluid-filled blisters or red, painful, burning or itching sores on or near the mouth, or on fingers.
• Swollen, sensitive gums of a deep red color.
• A fever, flu-like symptoms, and swollen lymph nodes in the neck often accompanying the first attack. Recurrent sores usually don't produce these symptoms.
• Tingling and itching in the area of a previous outbreak may be symptoms of a recurrence.

Call Your Doctor About Cold Sores If:

• You develop a high fever or chills; high fevers can be dangerous.
• Your sores are very painful; you may be able to get prescription relief.
• You have early signs of infection. Antiviral agents may shorten the course of illness only if started early.
