Is any of this happening now?
Call 911
Call emergency services if a seizure lasts five minutes or longer, another seizure begins before recovery, breathing is difficult, a serious injury occurs, or the person does not return to their usual level of awareness.
Sudden weakness, severe confusion, loss of consciousness, or breathing difficulty also needs emergency care.
These symptoms should not be assumed to be part of the skin condition.
Other emergency signs, for anyone

Does any of this apply?
Book an appointment
Arrange a routine medical appointment if you or your child has an unexplained pale streaked or whorled skin pattern.
An assessment is particularly useful when the markings appeared in infancy or are accompanied by developmental, movement, vision, dental, or skeletal differences.
Every sign above is quoted from the sofidex article on Hypomelanosis of ito. If you are not sure, err upward — it is always reasonable to be checked.
