The lesions look most consistent with folliculitis or ingrown hairs: inflamed hair follicles causing small red bumps, a few with tiny white pustules. Friction, sweating, tight clothing, shaving/waxing, or bacterial overgrowth can trigger this. Folliculitis is an infection/inflammation of hair follicles and often appears as follicle-centered pustules (Andrews' Diseases of the Skin E-Book: Clinical Dermatology, p. 301).
A photo cannot confirm the diagnosis, and genital herpes or another infection should be excluded if the bumps are painful, become grouped fluid-filled blisters, turn into open sores, recur, or there has been recent sexual exposure. Herpes is more often painful or burning than simply itchy.
What to do now
- Do not shave, wax, scratch, or squeeze the bumps.
- Wash gently once daily, dry the area well, and wear loose cotton underwear.
- Avoid fragranced soaps, intimate washes, deodorants, and strong steroid combination creams.
- Arrange an in-person review with a gynecologist or dermatologist within a few days, especially if it is spreading or not improving. They may examine it and, if needed, take a bacterial or HSV swab before prescribing treatment.
Seek urgent care today if there is fever, rapidly spreading redness, marked swelling, severe pain, pus-filled boils, trouble urinating, ulcers, or if you are pregnant/immunocompromised.
