Diagnosis and treatment
I can’t diagnose from a photo alone, but this looks concerning for an infected skin lesion (possible impetigo/secondary bacterial infection on eczema or a fungal rash).
Because it is on the hand and appears crusted/inflamed, it should be examined today by a clinician.

What to do now
- Clean gently with mild soap and water 1-2 times/day.
- Do not scratch or pick; keep nails short.
- Apply a plain petroleum jelly layer and cover with non-stick gauze.
- Avoid steroid creams until a doctor confirms diagnosis (steroids can worsen some infections, especially fungal).
- Do not share towels/clothes; wash hands often.
Likely treatment (depends on exam)
A doctor may prescribe one of these based on findings:
- Bacterial infection (impetigo/cellulitis): topical or oral antibiotics
- Fungal infection (tinea): topical antifungal; avoid steroid combinations
- Eczema with secondary infection: anti-inflammatory treatment plus antimicrobial therapy if infected
Red flags -> urgent care / ER now
- Fever
- Rapidly spreading redness/swelling
- Severe pain, warmth, pus, foul smell
- Red streaks up the hand/arm
- Trouble moving fingers
- Child is very unwell, diabetic, or immunocompromised
If you want, I can help you with a step-by-step home care plan for the next 24 hours and what to tell the doctor at visit.
