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

Does any of this apply?
Book an appointment
Arrange a routine appointment if you develop ongoing tingling, burning, numbness, unexplained weakness, balance problems, digestive changes, or dizziness when standing.
New bladder or sexual symptoms also deserve assessment.
These symptoms may have causes other than diabetic neuropathy.
Every sign above is quoted from the sofidex article on Diabetic neuropathy. If you are not sure, err upward — it is always reasonable to be checked.
