Causes

Cramps or spasms in the muscles often have no clear cause.

Possible causes of hand or foot spasms include:

• Brain disorders, such asparkinson's disease,multiple sclerosis, dystonia, and Huntington's disease.
• Chronic kidney disease and dialysis
• Damage to a single nerve or nerve group (mononeuropathy) or multiple nerves (polyneuropathy) that are connected to muscles
• Dehydration (not having enough fluids in your body)
• Disorders or injuries that involve peripheral nerves
• Heavy exercise
• Hyperventilation (overbreathing), which is rapid or deep breathing that can occur with anxiety or panic
• Increased levels of phosphate in the body
• Muscle cramps, usually caused by overuse during sports or work activity
• Pregnancy, more often during the third trimester
• Reduced levels of magnesium or calcium in the body
• Thyroid disorders
• Too little vitamin D
• 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.

There are stretching exercises you can do. These stretches will help keep your muscles from getting shorter or tighter.

Being active will also help keep your muscles loose. Aerobic exercise, especially swimming, and strength building exercises are both helpful. Playing games and sports and doing daily tasks may also help, but can also make matters worse if done to excess.

Drinking plenty of fluids during exercise is also important.

When to Contact a Medical Professional

Blood and urine tests may be done. Tests may include:

• Calcium and magnesium levels
• Hormone levels
• Kidney function tests
• Vitamin D levels (25-OH vitamin D)
