What should I do if skin is broken during gua sha?

Patients with skin abrasions after gua sha are advised to immediately stop the procedure to avoid further injury. Clean the affected area gently with a mild cleanser to prevent infection, then apply an appropriate amount of antibacterial ointment, such as erythromycin ointment, to help prevent infection. Strictly avoid exposing the injured area to water or other contaminants and keep it dry. If symptoms continue to worsen or signs of infection—such as redness, swelling, or pain—develop, seek medical attention promptly.
