Symptoms of Cold Sores
Cold sore symptoms vary greatly from one person to another. When you are first infected with HSV-1, you may have no symptoms at all. Others have a severe cold sore accompanied by flu-like symptoms.
Symptoms may include:
- Tingling of the lips
- Dry or irritated skin on the lips and mouth
- Small blisters on the lips, gums, roof of the mouth or inside of the cheeks
- Crusted-over sore that lasts up to three weeks
- Swollen lymph glands
- Muscle aches
If the herpes simplex virus has spread to your eyes, you may also experience:
- Swollen lids
- Pain or burning
- Sensitivity to light
Symptoms usually appear between 2 and 20 days after exposure to the virus. The blisters can last up to three weeks. Subsequent cold sores may heal more quickly.
