Bumps and Itchy Skin

Dry, rough, cracked areas often accompany eczema or irritant dermatitis. A new product, fabric, medicine, or plant can trigger contact dermatitis. Raised areas that appear suddenly and move or fade may be hives. Small intensely itchy bumps, especially with night-time symptoms or affected household contacts, can occur with scabies. Scaling in warm, moist folds may occur with a yeast infection, while psoriasis can form persistent sharply bordered plaques. Location, duration, skin colour changes, pain, and any fluid or crust help a clinician narrow the possibilities.

Use a mild fragrance-free cleanser, moisturise after washing, and keep nails short to reduce damage from scratching. Wear soft, breathable clothing and avoid hot showers, rubbing, and newly introduced products until the cause is clearer. A cool compress may calm itching. Avoid borrowing prescription creams or applying multiple treatments at once; some products can worsen infection or make the rash harder to recognise. Take a clear photo if the appearance changes quickly and record possible triggers.

Seek urgent help if itching comes with swelling of the lips or tongue, breathing difficulty, faintness, or widespread blistering. Arrange prompt assessment for fever, rapidly spreading warmth or redness, pus, severe tenderness, purple or dark spots that do not fade with pressure, or sores involving the eyes or mouth. See a clinician when the rash persists, repeatedly returns, disrupts sleep, or affects other people in the household.

What features make one cause more likely than another? Could a medicine, product, bite, or exposure be responsible? Do I need testing or a prescription treatment? How can I control the itch without damaging the skin, and which warning signs should make me return sooner?
