Jewelry rash: causes and next steps

A rash beneath a ring, watch or necklace may be red, itchy, scaly, cracked or weepy. Metal allergy, trapped soap, sweat and friction are common explanations. A rash that extends beyond the contact outline may need a broader assessment. Depending on its features, a clinician may consider contact dermatitis, atopic dermatitis, psoriasis, heat rash, intertrigo, ringworm, scabies or a drug rash. Location alone cannot identify the cause.

Remove the jewelry and gently rinse away soap or sweat; pat dry rather than rubbing. Do not share creams, scratch the area or reapply the item to test it while the skin is inflamed. Photograph the rash and record when it appeared, what touched the skin and whether symptoms followed a new product or medicine. If it returns or does not settle, a clinician can examine the border, scale and distribution and may arrange allergy testing.

Get medical advice for persistent, spreading, painful or recurrent redness, especially if the skin is cracked or draining. Seek urgent help for swelling of the lips or face, trouble breathing, faintness or a rapidly spreading blistering rash. Fever, increasing warmth, pus or red streaks can signal infection and need prompt assessment.

Ask whether the pattern fits an allergy, irritation, infection or another dermatitis; whether patch testing is appropriate; and which cleanser or treatment is suitable. Tell the clinician about new jewelry, cosmetics, adhesives and medicines.
