Is any of this happening now?
Call 911
Call emergency services for sudden facial drooping, one-sided weakness, difficulty speaking, or sudden loss of coordination, as these can be signs of a stroke rather than metabolic neuropathy.
Emergency assessment is also needed for rapidly spreading weakness, inability to walk, new loss of bladder or bowel control with numbness around the groin, trouble swallowing, or breathing difficulty.
And for anyone, someone who:
has sudden weakness or drooping on one side of the face or body, slurred speech, or sudden confusion
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 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
Someone who you believe has taken an overdose or swallowed something poisonous

Does any of this apply?
Book an appointment
Arrange a routine appointment if you develop persistent tingling, numbness, burning pain, unexplained weakness, or balance problems.
Earlier assessment may identify a treatable cause before further nerve damage occurs.
Every sign above is quoted from the sofidex article on Metabolic neuropathies. If you are not sure, err upward — it is always reasonable to be checked.
