Impetigo on the Wrist: What to Know

A wrist lesion may start as a small red spot, blister, or shallow sore before leaking fluid and forming a crust. Watches, bracelets, sports equipment, and repeated rubbing can irritate the skin and make touching more likely. Scratching can transfer bacteria to other areas or to another person. Keep jewellery and straps away from the lesion until the skin has been assessed. If the wrist is also itchy and dry, an underlying condition such as [Atopic Dermatitis](/conditions/atopic-dermatitis/) may have weakened the skin barrier, but a clinician must confirm the cause.

Clean the area gently, pat it dry, and cover it with a clean dressing if it rubs against clothing or is likely to be touched. Change the dressing as advised, wash hands after care, and launder towels and clothing that contact the sore. Do not share towels, watches, or sports gear. Medical treatment may involve a prescribed topical antibiotic for a limited area or an oral medicine when infection is broader. See [Topical Antibiotic Therapy](/treatments/medical-dermatology/topical-antibiotic-therapy/) for context.

Get medical advice if redness is expanding, the wrist becomes increasingly warm or swollen, movement hurts, pus continues, or new sores appear. Prompt assessment is warranted with fever, red streaks moving up the arm, or feeling faint or unwell. These features may signal a deeper or spreading infection and should not be managed by picking or squeezing.

Ask what caused the skin break, which treatment suits the affected area, whether a dressing is needed, and how long to avoid shared equipment or close skin contact.
