Herpes typically looks like small, fluid-filled blisters or shallow sores that form in clusters on red, irritated skin. These lesions most often appear on the genitals, anus, or around the mouth, and they can sting, itch, or burn before breaking open and then crusting as they heal. See more details on common genital herpes symptoms.
A first outbreak can be more widespread and painful, and some people also feel unwell with low fever, body aches, or swollen groin nodes. Later flare-ups tend to be milder and clear faster, with fewer sores that follow the same pattern of blisters, open sores, and scabs.
Herpes is contagious when sores are present. It is important to avoid sexual contact until the skin has fully healed, since condoms may not completely block contact with fluid from the sores. Treatment focuses on comfort and faster healing with antivirals when needed. Read more about how genital herpes is treated and the options your doctor may discuss with you.
Anyone who thinks a sore could be herpes should seek medical care for testing and personalized guidance. A dermatologist, gynecologist, or urologist can confirm the diagnosis and recommend safe treatment. Do not self-medicate, avoid picking at blisters, and wash hands after touching the area to reduce the risk of spreading the virus.
