The blisters are usually in clusters, but you might have just one blister. You might have a fever, muscle aches, and sore lymph nodes in the groin area. Herpes sores can cause vaginal discharge in women.

Does herpes come in clusters or just one bump?

Both pimples and genital herpes appear as clusters of red bumps. They may both feel itchy or irritated, and they can both show up on your butt, too. Pimples and herpes each have distinct symptoms, though.

Are herpes sores grouped together?

They are tiny, fluid-filled blisters on and around your lips. These blisters are often grouped together in patches. After the blisters break, a scab forms that can last several days. Cold sores usually heal in two to three weeks without leaving a scar.
