What is tetany?

Tetany is a condition that involves involuntary muscle contractions and overly stimulated peripheral nerves. It's caused by electrolyte imbalances — most often low blood calcium levels.

Symptoms of tetany

  • Numbness of the fingers

  • Muscle pain

  • Numbness or abnormal sensation

  • Decreased sensation over skin

  • Eyelids keep twitching

  • Tingling or prickling sensation of the skin

  • Leg muscle pain

Questions your doctor may ask to check for tetany

Your doctor may ask these questions to diagnose tetany

  • Do you have numbness from your wrist down?

  • Do you have any muscle pain?

  • Do you feel any numbness or change in sensation?

  • Do you feel the sensation on your skin has changed?

  • Do you have eyelid twitching or squeezing of the eyes?

Treatment for tetany

The short-term goal for treating tetany is to fix the electrolyte imbalance. The long-term goal for treating tetany is diagnosing and treating the underlying condition causing it.
