Herpes can lay dormant (sort of like it’s in hibernation) for years without causing any noticeable symptoms. Because of this, many people don’t know they have it and may have trouble figuring out how or when they got it. When symptoms do occur, they often appear as small blisters on or around the genitals. The blisters may look like pimples with clear fluid in them, and they may be painful or have a burning sensation. The best way to find out if you have herpes is to see a health care provider if you think you’ve been exposed to it or if you have pain, blisters, or a sore.
