Is any of this happening?
Be seen today
Arrange a prompt medical assessment if a hemangioma:
Is growing quickly, especially in a young infant
Is close to an eye, eyelid, nose, mouth, ear, or genital area
Interferes with feeding, hearing, movement, or opening an eye
Becomes painful, crusted, or develops an open sore
Shows spreading redness, swelling, pus, or other signs of infection
Appears as five or more separate skin hemangiomas in an infant
Is large and covers a broad area of the face, scalp, lower back, or pelvis
Urgent assessment may be needed for unusual sleepiness, shaking, sweating, breathing difficulty, or poor responsiveness because these can be signs of low blood sugar or another medicine-related problem.
