Genital herpes symptoms

Genital herpes is a highly contagious STI caused by a type of the herpes simplex virus (HSV) that enters your body through small breaks in your skin or mucous membranes. Most people with HSV never know they have it, because they have no signs or symptoms or the signs and symptoms are so mild they go unnoticed.

When signs and symptoms are noticeable, the first episode is generally the worst. Some people never have a second episode. Others, however, can have recurrent episodes for decades.

When present, genital herpes signs and symptoms may include:

  • Small red bumps, blisters (vesicles) or open sores (ulcers) in the genital and anal areas and areas nearby
  • Pain or itching around the genital area, buttocks and inner thighs

Ulcers can make urination painful. You may also have pain and tenderness in your genital area until the infection clears. During an initial episode, you may have flu-like signs and symptoms, such as a headache, muscle aches and fever, as well as swollen lymph nodes in your groin.

In some cases, the infection can be active and contagious even when sores aren't present.
