Muscular atrophy
Muscular atrophy


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

Alternative Names:

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


Spasms of the hands or feet may be an important early sign of tetany, a potentially life-threatening condition. Tetany is due to a problem with the body's calcium levels, which can be linked to the following:

The spasms are usually accompanied by the following symptoms:

  • Cramping
  • Fatigue
  • Muscle weakness
  • Numbness, tingling, or a "pins-and-needles" feeling
  • 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)
  • Hypomagnesemia (low magnesium levels in the blood)
  • Thyroid disorders
  • Dystonia
  • Huntington's disease
  • Hyperventilation -- calcium becomes temporarily less available to the body during hyperventilation
  • Damage to a single nerve or nerve group (mononeuropathy ) or multiple nerves (polyneuropathy) that are connected to muscles
  • Multiple sclerosis
  • Use of certain 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.

  • 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 do you have?
    • 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?
