Common causes
- 1
Eczema (atopic dermatitis)
Very itchy pink-red rash with dryness and scale on inner elbows, backs of knees, hands, neck. Recurs in flares.
- 2
Hives (urticaria)
Raised itchy welts that come and go within 24 hours. Triggers include food, medication, infection, heat, and stress.
- 3
Contact dermatitis
Itchy red patch, sometimes with tiny blisters, exactly where skin touched an irritant (soap, plant, nickel, fragrance).
- 4
Fungal rash
Ring-shaped itchy rash with a raised scaly edge — common in warm folds, feet, or after sharing towels.
- 5
Scabies
Intensely itchy rash worse at night, with tiny burrow lines in finger webs, wrists, waistband. Contagious — needs prescription treatment.
- 6
Insect bites
Isolated itchy bumps, often in clusters on exposed skin, appearing overnight.

When to see a doctor
Seek medical care if you notice any of these
- Rash with fever, joint pain or feeling unwell
- Facial or lip swelling, or trouble breathing
- Rapid spread over hours
- Non-blanching purple spots
- No improvement after 2–4 weeks of self-care
What to do at home
These self-care steps are safe to try for 2 weeks while you monitor the area. If the skin gets worse or matches any red flag above, see a clinician instead.
- 1
Photograph the area today in bright, indirect light so you can track any change in 2 weeks.
- 2
Stop any new soap, cream, cosmetic, laundry detergent or medication started in the last 2 weeks.
- 3
Apply a cool compress for 10 minutes, twice a day, if the skin is itchy or inflamed.
- 4
Use a fragrance-free moisturiser twice daily to support the skin barrier.
- 5
Avoid scratching, picking, or scrubbing — it worsens most rashes and risks infection.
- 6
Take an over-the-counter oral antihistamine (e.g. cetirizine) if itching disturbs sleep.

Frequently asked questions
Cool compresses for 10 minutes, then fragrance-free moisturiser and an oral antihistamine. Stop any new soap, cream or medication started in the past two weeks. Avoid scratching — it worsens the rash and risks infection.
Eczema, hives and contact dermatitis are not contagious. Fungal rashes and scabies are contagious and need specific treatment.
Book a review if the rash covers a large area, blisters, oozes, comes with fever, or does not improve in 2–4 weeks. Seek same-day care for facial swelling, breathing trouble, or non-blanching purple spots.
Stress does not cause a rash from nothing, but it can trigger flares of eczema, hives, and psoriasis in people already prone to them.
