Go through these in order and stop at the first one that applies. If you are reading this for someone else, answer for them.
Call emergency services for trouble breathing, fainting, chest pain, severe confusion, or swelling of the tongue or throat.
Contact the treating team promptly for increasing pain after initial improvement, spreading redness, worsening swelling, pus, bad odour, fever, or a dressing soaked with ongoing bleeding.
New clusters of painful blisters, especially around the mouth or eyes, may need urgent antiviral treatment.
Seek urgent medical assessment for severe swelling that closes an eye, new vision changes, rapidly darkening skin, or bleeding that does not stop with the method your team provided.
Routine questions about persistent redness, itching, shaving, makeup, exercise, or restarting skin products can usually wait for the clinic’s normal hours or your planned follow-up.
