Hand or foot spasms

Definition

Spasms are contractions of the hands, thumbs, feet, or toes that are sometimes seen with muscle cramps, twitching, and convulsions (tetany). They can be severe and painful.

Alternative Names

Foot spasms; Carpopedal spasm; Spasms of the hands or feet

Considerations

Spasms of the hands or feet may be an important early sign of tetany, a potentially life-threatening condition. Tetany is a manifestation of an abnormality in calcium level, which can be linked to the following:

• Lack of vitamin D
• Lessened function of the parathyroid glands (hypoparathyroidism)
• Alkalosis in the body
• Ingestion of alkaline salts

These spasms are usually accompanied by the following symptoms:

• Numbness, tingling, or a "pins-and-needles" feeling
• Muscle weakness
• Fatigue
• Cramping
• Twitching
• Uncontrolled, purposeless, rapid motions

Common Causes

• Muscle cramps, usually caused by sports or occupational muscle injury
• Parkinson's disease
• Hypocalcemia (low calcium levels in the blood)
• Hypermagnesemia (high magnesium levels in the blood)
• Thyroid disorders
• Dystonia
• Huntington's disease
• Hyperventilation -- calcium becomes temporarily unavailable to the body during hyperventilation
• Damage to a single nerve or nerve group (mononeuropathy) or multiple nerves (polyneuropathy)
• Multiple sclerosis
• Various medications

Home Care

If vitamin D deficiency is the cause, supplemental vitamin D should be taken under the doctor's direction. Calcium supplements may also help.

Call your health care provider if

If you notice recurrent spasms of your hands or feet, call your health care provider.

What to expect at your health care provider's office

Your provider will obtain your medical history and will perform a physical examination. Laboratory testing of blood and urine may also be done.

Medical history questions documenting hand or foot spasms in detail may include the following:

• Do the spasms appear to be involuntary or purposeless?
• Are they prolonged?
• At what age did the spasms first appear?
• Does the presence of spasms seem variable over weeks to months?
• Do spasms occur repeatedly (recurrent)?
• Do several spasms occur in a row (repetitive)?
• Are the spasms slow or rapid?
• Can the spasms be voluntarily suppressed?
• How long have you had spasms?
• Is it worse when you exercise?
• How much calcium-containing food do you eat (such as milk products)?
• What have you done to try to treat the spasms? How effective was it?
• What other symptoms are also present?
  • Do you have numbness or a "pins-and-needles" feeling?
  • Do you have muscle weakness?
  • Do you have fatigue?
  • Do you have muscle cramps elsewhere?
  • Do you have seizures?

Diagnostic tests may include the following:

• Blood tests to measure magnesium and calcium levels
• Hormone levels
• Kidney function tests
• Vitamin D levels (25-OH vitamin D)
