The affected area may appear red, inflamed, or tender.
Depending on the location, sores can make everyday activities uncomfortable.
For example:
-
Walking may cause friction against genital lesions.
-
Urination may become painful if urine touches an open sore.
-
Sexual activity may cause significant discomfort.
-
Sitting may become uncomfortable when lesions affect the buttocks or nearby skin.
The healing process generally occurs gradually.
The sores may develop a crust or dry surface before the skin heals.
However, genital herpes does not always produce classic blisters.
Some infections cause tiny cracks, mild redness, or small ulcers that are easily mistaken for other skin conditions.
A painful genital ulcer should always be evaluated because several sexually transmitted infections can produce similar symptoms.
Syphilis, for example, can cause genital sores, although its typical primary lesion is often painless.
Other causes include trauma, inflammatory conditions, and certain bacterial or viral infections.
4. Swollen Lymph Nodes May Accompany an Infection
The lymphatic system helps the body recognize and respond to infections.
Lymph nodes are small structures that filter lymph fluid and contain immune cells.
When an infection develops, nearby lymph nodes may become enlarged or tender.
In people experiencing a first episode of genital herpes, lymph nodes in the groin may become swollen.
This can happen because the immune system is responding to the infection.
Other symptoms may include:
-
Tenderness in the groin.
-
Localized swelling.
-
Fever.
-
Headaches.
-
Muscle aches.
-
General discomfort.
Swollen lymph nodes are not unique to herpes.
They can occur with bacterial infections, other viral infections, skin injuries, and several medical conditions.
Persistent, rapidly enlarging, or unexplained lymph node swelling should be assessed by a healthcare professional.
5. Genital Bumps Are Not Always Herpes: Other Conditions to Recognize
One of the biggest mistakes people make is assuming that every bump around the genital area represents a sexually transmitted infection.
Several conditions can produce similar appearances.
Understanding the differences is useful, but visual identification alone is not reliable enough to establish a diagnosis.
Molluscum Contagiosum
Molluscum contagiosum is a viral skin infection caused by a poxvirus.
It produces small, round, raised bumps that often have a distinctive central indentation.
The bumps may be:
-
Skin-colored.
-
Pink.
-
White.
-
Smooth.
-
Firm.
They are usually painless, although irritation and inflammation can occur.
Molluscum can affect children and adults.
In adults, lesions around the genital area may spread through sexual skin-to-skin contact.
However, not every case involving the genital area is sexually transmitted.
The infection can also spread through direct skin contact and contaminated objects.
In many healthy individuals, molluscum eventually resolves without treatment, although this may take months or longer.
A healthcare professional can recommend treatment when lesions are numerous, persistent, uncomfortable, or located in sensitive areas.
Genital Warts (HPV)
Genital warts are caused by certain types of human papillomavirus (HPV).
They may appear as:
-
Small raised bumps.
-
Flat growths.
-
Smooth or rough lesions.
-
Clusters resembling cauliflower.
Some are very small and difficult to notice.
Others gradually become larger or multiply.
Genital warts are often painless, although itching, irritation, or occasional bleeding can occur.
HPV spreads through intimate skin-to-skin contact.
Some HPV types cause genital warts, while other types are associated with cancers of the cervix, anus, penis, vulva, vagina, and throat.
Importantly, the HPV types that usually cause genital warts are generally different from the types responsible for most HPV-related cancers.
Vaccination can protect against several important HPV types.
Folliculitis
Folliculitis is inflammation of hair follicles.
It can produce small red bumps or white-tipped pustules that resemble acne.
Common contributing factors include:
-
Shaving.
-
Friction.
-
Sweat.
-
Tight clothing.
-
Bacterial infection.
-
Irritation around hair follicles.
Folliculitis may affect the thighs, groin, buttocks, beard area, and other parts of the body.
Unlike herpes, folliculitis typically develops around hair follicles.
However, the appearance can overlap, particularly when lesions become inflamed.
Treatment depends on the cause and may involve avoiding irritation, improving skin hygiene, or using prescribed medications.
Syphilis
Syphilis is a sexually transmitted bacterial infection caused by Treponema pallidum.
During its primary stage, it commonly causes a sore called a chancre.
This sore is typically:
-
Firm.
-
Usually painless.
-
Often round.
-
Associated with the area where the bacteria entered the body.
It may heal without treatment.
However, this does not mean the infection has disappeared.
Without appropriate antibiotics, syphilis can progress to later stages and potentially damage the nervous system, heart, blood vessels, and other organs.
