What Is Anal Herpes?

Both types can infect the anal area.
Where it can appear:

- Inside the anal canal
- On nearby skin (buttocks, upper thighs)
What Does Anal Herpes Look Like?
Classic appearance:
Anal herpes typically presents as:
- Small, fluid-filled blisters
- Grouped together
- On red or inflamed skin
As it progresses:
- Blisters break open
- Form painful sores (ulcers)
- Then crust and heal
Important variation:
Not all cases look “textbook.”
You may see:
- A single sore
- Small cracks in the skin
- Mild redness
- Lesions mistaken for hemorrhoids or irritation
