Folliculitis, herpes, and genital warts can all show up as bumps below the belt, but they're caused by completely different things: folliculitis is an inflamed or infected hair follicle, genital herpes is a viral infection that produces painful blisters and sores, and genital warts are soft, flesh-colored growths caused by HPV. You usually can't tell them apart by sight or feel. A test settles it.

What each one is
Folliculitis
Folliculitis is inflammation of a hair follicle, usually from bacteria, friction, or irritation after shaving or waxing. It is not a sexually transmitted infection. The bumps tend to sit right where hair grows — the pubic mound, scrotum, labia, or inner thighs — and often look like small red pimples, sometimes with a white head and a hair poking through the center. It can itch or sting, and it frequently clears on its own once the skin is left alone. Because it mimics the early bumps of herpes and warts, it's worth keeping in mind as a third explanation.
Genital herpes
Genital herpes is caused by two viruses, herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) CDC. Once you're infected, the virus stays in your body for life, living quietly in nerve roots and reactivating from time to time. Most people have no symptoms or very mild ones and never recognize what they have. Most HSV-2 infections go undiagnosed, so it spreads widely without anyone meaning to pass it on.
HPV & genital warts
HPV is the most common STI CDC. There are many strains. Low-risk types cause genital warts, while high-risk types can, over years, drive cancer. Genital warts usually appear as a small bump or a group of bumps in the genital area; they can be flat, raised, or cauliflower-shaped. High-risk HPV is typically silent. Most HPV infections cause no symptoms and no clinical disease, and the immune system clears many of them on its own.
Symptoms compared
The clearest differences are in how the lesions feel and how they change over time, though there's real overlap.
- Herpes: A first outbreak often starts with blisters that break into painful, open sores, which take a week or more to heal. Flu-like symptoms — fever, body aches, swollen glands — can come with that first episode. Sores appear on or around the genitals, rectum, or mouth. Repeat outbreaks are shorter and milder, and some people feel a warning prodrome (tingling, itching, or burning) a day or two before lesions appear.
- Genital warts: Painless soft bumps, often clustered, that don't blister, ooze, or scab over the way herpes does. They can itch but rarely hurt — we cover the nuances in do warts hurt.
- Folliculitis: Small, tender or itchy red bumps centered on hair follicles, sometimes pus-tipped, that come and go with shaving and usually resolve without treatment.
How to tell them apart
A few features point a clinician in the right direction. Pain and a blister-to-ulcer sequence lean toward herpes. A painless, persistent bump that's slowly growing leans toward a wart. A bump built around a hair that appears after shaving and fades on its own leans toward folliculitis. None of these is reliable enough to bet your health on. Herpes can be nearly painless, warts can be irritated and tender, and an infected follicle can look alarming. The symptoms overlap enough that you usually can't tell them apart by feel, and a test gives you the answer.

Side-by-side comparison
| Folliculitis | Genital herpes | Genital warts (HPV) | |
|---|---|---|---|
| Cause | Inflamed/infected hair follicle (not an STI) | HSV-1 or HSV-2 (virus) | HPV (virus) |
| Looks like | Red bump, often with a hair or whitehead | Blisters that break into sores | Soft flesh-colored bumps, may cluster |
| Pain | Mild tenderness or itch | Often painful, especially first outbreak | Usually painless, may itch |
| Course | Often clears on its own | Heals then recurs; virus stays for life | Persists or grows until treated; may recur |
| Contagious | No (not sexually transmitted) | Yes, including with no visible sore | Yes, by skin-to-skin contact |
| How it's confirmed | Clinical exam | Swab of a lesion (NAAT or culture) | Visual exam by a clinician |
Testing
What testing looks like depends on what's suspected: a urine sample, a self-collected swab, or a quick exam. Much of it is free or low-cost at health departments, Planned Parenthood, and Title X clinics. For herpes, the best confirmation when you have an active lesion is type-specific virologic testing of the sore itself — a swab analyzed by NAAT or culture CDC. Swab-based tests work best, so it helps to be seen while a lesion is present. For warts, diagnosis is usually visual: a clinician identifies them on exam. There's no routine HPV test for men, adolescents, or women under age 30 CDC, so HPV screening is a cervical-cancer screening tool and won't check a bump. Folliculitis is diagnosed by exam alone.
If you've had a possible exposure, timing matters — read when to test after exposure before you book, and you can get tested when you're ready.
Treatment compared
Each condition is managed differently because the underlying cause is different.
- Folliculitis often improves with gentle skin care and by pausing shaving; mild cases may not need any prescription.
- Herpes has three FDA-approved antivirals — acyclovir, valacyclovir, and famciclovir — that control symptoms but do not cure the infection CDC. They can be taken to shorten an outbreak or daily to suppress them. Daily suppression also protects partners: in a randomized trial of serodiscordant couples, suppressive valacyclovir lowered the risk of passing HSV-2 to a partner by about 48% Corey et al., NEJM. If you're weighing your options, see alternative herpes treatments.
- Genital warts can be treated with patient-applied creams and solutions, including imiquimod 3.75% or 5% cream, podofilox 0.5% solution or gel, and sinecatechins 15% ointment CDC. Sinecatechins are not recommended for immunocompromised or HIV-positive patients. Clinic-applied procedures are another route. Treating the warts you can see does not erase the underlying HPV.
The HPV vaccine matters here as prevention rather than treatment: given at the recommended ages, it can prevent more than 90% of HPV-caused cancers, and Gardasil 9 is about 98% effective against the precancers caused by HPV 16 and 18 American Cancer Society. HPV's cancer toll reaches well beyond the cervix. It causes virtually all cervical cancer, over 90% of anal cancers, and about 70% of throat (oropharyngeal) cancers, and oropharyngeal cancer has now overtaken cervical as the most common HPV-related cancer in the US NCI.
Can you have more than one at once?
Yes. These conditions aren't mutually exclusive, and having one doesn't protect you from the others. You could have irritated follicles from shaving and a herpes outbreak in the same area, or warts alongside an unrelated infection. That overlap is another reason not to self-diagnose from a single bump. A clinician can sort out whether you're dealing with one problem or several.
When to see a clinician
Get evaluated if a bump or sore is painful, blistering, spreading, not healing within a week or two, recurring in the same spot, or appearing after a new sexual partner. Painless bumps that persist or slowly grow are also worth checking, since warts don't go away on their own the way an irritated follicle does. Herpes can also spread when nothing is visible — people with HSV-2 shed virus on about 10% of days with no outbreak, most of it leaving no sore at all JAMA — so an exam during a quiet period is still worthwhile if you've had a possible exposure.
