Foot and hand cramping may be caused by abnormal levels of minerals or electrolytes in the body; brain disorders such as Huntington's disease, multiple sclerosis and Parkinson's disease; dialysis and chronic kidney disease; damage to a nerve group, a single nerve or multiple nerves that are connected to the muscles; and dehydration, explains the U.S. National Library of Medicine. Other factors that can also cause this condition are hyperventilation, use of certain medication, too little vitamin D and thyroid disorders.
Symptoms of hand and foot cramping depend on the cause, explains the U.S. National Library of Medicine. Some of the symptoms a patient may experience are uncontrolled and rapid motions, twitching, numbness or tingling, muscle weakness and fatigue. Leg cramps at night are more common in the elderly.
If the cause of the cramping of hands and feet is vitamin D deficiency, the patient should take supplemental vitamin D under doctor’s instructions, explains the U.S. National Library of Medicine. Calcium supplements may also help. A good home care recommendation is to keep muscles loose. This means getting involved in aerobic exercises such as swimming and strength building. However, overdoing these activities may worsen the condition. If the cramping or spasms of the hand and feet continue, consider consulting a health care provider for evaluation
