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
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
