Spasms may be accompanied by numbness, tingling, loss of function, and pain in affected muscle groups.

Characteristic signs include Trousseau sign, Chvostek sign, and the peroneal sign. Prolongation of the isoelectric phase of the S-T segment of the electrocardiogram may be present with tetany that is caused by a low serum calcium level.
