American Academy Dermatology folliculitis self care when see dermatologist
The bumps in the photo appear mostly centered around hair follicles, with a few dry, scratched/scabbed spots. This can fit folliculitis or shaving-related irritation/ingrown hairs, especially if this area is shaved, sweaty, rubbed by clothing, or recently exposed to a new body product. Other possibilities include an irritated eczema-type rash, insect bites, or scabies if itching is intense and others nearby are also itchy. A photo cannot confirm the cause.
What to do now
- Stop shaving or closely trimming the area until it clears. Do not pick the white/dry scabs.
- Wash gently once daily, shower after sweating, and wear loose breathable clothing.
- Avoid fragranced lotions, harsh scrubs, oils, and steroid-antifungal combination creams unless a clinician tells you to use them.
- A benzoyl peroxide 2.5% to 5% body wash can be tried once daily for 1 to 2 weeks if the bumps are follicular or pimple-like. Rinse well, stop if it burns or worsens dryness, and note that it can bleach fabrics.
- Use a bland, fragrance-free moisturizer on the dry areas.
Arrange an in-person clinician or dermatologist visit if it is spreading, recurrent, lasting beyond 1 to 2 weeks, very itchy, or not improving. A clinician may need to examine for bacterial versus yeast folliculitis, dermatitis, scabies, or another cause before prescribing treatment. Folliculitis is often associated with S. aureus, but yeast and other triggers can also cause it.
Seek prompt care if you develop increasing pain, warmth, swelling, pus, fever, red streaks, or boil-like lumps.
Is it itchy or painful, and did it start after shaving, sweating, a new soap/product, or contact with someone else who has an itchy rash?
What symptoms would suggest infection or scabies?

CDC scabies symptoms intense itching burrows infection signs skin
Signs suggesting a bacterial skin infection
Look for:
- Increasing redness, warmth, swelling, or tenderness
- Pus or yellow/honey-colored crusting, fluid drainage, or painful whiteheads
- Bumps becoming larger, deeper, or boil-like
- Redness spreading beyond individual bumps or red streaks
- Fever, chills, or feeling unwell
Get urgent same-day medical care for rapidly spreading redness, severe pain, fever, red streaks, or a large painful swollen lump. Scratching can break the skin and allow bacteria to cause a secondary infection, as described by the CDC scabies guidance.
Signs suggesting scabies
Scabies is more likely if there is:
- Very intense itching, especially at night
- Many small itchy bumps, often with scratch marks
- Tiny, thin, slightly raised wavy or zig-zag burrow lines, skin-colored or gray-white
- Distribution on the finger webs, wrists, elbows, armpits, waistline, buttocks, genitals, nipples, or shoulder blades
- A close contact, housemate, or sexual partner with similar itching or rash
With a first scabies infection, symptoms can appear several weeks after exposure. The CDC symptom description and dermatology texts describe intense nighttime itch and small papules or pustules with excoriations as common findings. Book source: Fitzpatrick's Dermatology, Clinical Findings, lines 1311-1320.
In your photo, I do not see obvious burrow lines, and the bumps look more follicle-related than classic scabies. But scabies cannot be ruled out from one photo. If the night itch is strong or others in your household are itching, arrange an exam soon. Do not self-treat only one person if scabies is confirmed, because close contacts often need treatment at the same time.
