What are the symptoms of oral herpes

Oral herpes, also known as cold sores or fever blisters, is typically caused by the herpes simplex virus type 1 (HSV-1). Symptoms of oral herpes can vary from person to person, but they commonly include:

  1. Tingling or itching sensation: Before the appearance of blisters, many individuals experience tingling, itching, or burning sensations around the lips or mouth.
  2. Small, painful blisters: Clusters of small, fluid-filled blisters usually appear on or around the lips, though they can also occur inside the mouth, on the gums, or on the roof of the mouth. These blisters may break open, ooze fluid, and then crust over.
  3. Pain or discomfort: The blisters can be painful or uncomfortable, especially when eating, drinking, or talking.
  4. Swelling and redness: The affected area may become swollen and red.
  5. Fever and swollen lymph nodes: Some people may experience mild fever, headache, and swollen lymph nodes in the neck during a herpes outbreak.
  6. Recurrence: After the initial infection, the virus remains dormant in the body’s nerve cells and can reactivate periodically, causing recurrent outbreaks. These outbreaks may be triggered by factors such as stress, fatigue, sun exposure, hormonal changes, or a weakened immune system.

It’s worth noting that some individuals infected with HSV-1 may not experience any symptoms, or they may have very mild symptoms that go unnoticed. Additionally, oral herpes can be spread to others even when there are no visible symptoms present, as the virus can still be shed through saliva.
