Is any of this happening now?
Call 911
Seek emergency care if a foot suddenly becomes cold, pale or blue, very numb, or difficult to move.
These symptoms may indicate a serious problem with circulation or nerves rather than the high arch itself.
Other emergency signs, for anyone
Someone who is struggling to breathe, gasping, choking, or cannot get words out
Someone who has chest pain, tightness or pressure lasting more than a few minutes
Someone who has sudden weakness or drooping on one side of the face or body, slurred speech, or sudden confusion
Someone who is unconscious, or cannot be woken
Someone who is bleeding heavily and it will not stop with firm pressure
Someone who has had a seizure that will not stop, or does not wake up afterwards
Someone who has lips or skin that look pale, blue, grey or blotchy

Is any of this happening?
Be seen today
Seek prompt medical advice for broken skin, an ulcer, warmth, swelling, or drainage, particularly if you have diabetes, poor circulation, or reduced feeling in your feet.
Get urgent care after an injury if you cannot bear weight, the foot looks deformed, or pain and swelling are severe.

Does any of this apply?
Book an appointment
Arrange a routine appointment if:
Foot pain keeps returning or limits walking, work, or exercise
You have repeated ankle sprains
Calluses, curled toes, or difficulty fitting shoes are getting worse
The arch appears to be increasing
One foot has changed shape without a clear reason
You develop weakness, numbness, tingling, or balance problems
A child’s feet are changing or causing pain
Every sign above is quoted from the sofidex article on High arch. If you are not sure, err upward — it is always reasonable to be checked.
