Hand cramps usually happen as a temporary side effect of using your hands too much — after scrawling pages of notes during a grueling organic chemistry class, for instance, or hours of frantic typing to get a quarterly report finished in time.
“It’s all too easy to over-stress muscles in the hands from typing, writing, or working on your cell phone. Injuries and overuse can send inflammatory chemicals throughout the hands, contributing to cramps,” says Dr. Jacob Hascalovici, the Co-Founder & Chief Medical Officer of Clearing.
But persistent hand cramps that don’t have a clear cause can become more than a passing annoyance. They may cause lingering pain and discomfort and eventually begin to affect your day-to-day life.
Read on to learn four medical causes of hand cramps, plus a few steps you can take to get relief.
“In my experience, the most common causes of muscle cramps are dehydration and electrolyte imbalance,” says Dr. Mike Sevilla, a family physician at The Family Practice Center of Salem
Note: Dehydration happens when your body doesn’t have enough water to function as it typically would — such as when you don’t drink enough water, lose excessive fluid through exercise, or experience persistent vomiting and diarrhea during illness.
You might experience hand cramps when dehydrated because your muscles lose the proper balance of water and electrolytes.
Electrolytes like calcium, sodium, and potassium help regulate many cell functions, including how your muscles contract and relax, so losing electrolytes due to dehydration can cause cramps in your hands and arms, legs and feet, and your abdomen.
In addition to cramps in the hands and elsewhere, dehydration can cause:
What to do next: You can prevent dehydration and reduce your hand cramps by drinking enough water and taking in plenty of electrolytes — via liquids like coconut water, sports drinks, or Pedialyte — throughout the day.
Note: Experts recommend consuming between 11.5 cups to 15.5 cups of water each day. This recommendation includes the water you get from the food you eat — generally, about 20% of your daily fluids come from food, and the remaining 80% comes from water.
You’ll know you’re getting enough water throughout the day if you rarely feel thirsty and your urine is pale yellow to clear in color — and if your hand cramps improve.
Diabetes, a condition that affects how your body uses insulin, can cause muscle cramps throughout your body. These cramps most commonly affect your legs, but they can also develop in your hands.
Insulin regulates the amount of glucose — aka blood sugar — your cells can use for energy, so diabetes can affect various functions throughout your entire body.
Specific causes of hand cramps associated with diabetes include:
If you have uncontrolled diabetes, you’ll also experience other symptoms, such as:
Over time, diabetes can lead to a condition called diabetic cheiroarthropathy, which can cause hand cramps along with thickening skin on your hands. This condition, also known as stiff hand syndrome, occurs in about 30%-40% of people with diabetes.
Other symptoms of stiff hand syndrome include:
Note: The “prayer sign” is a distinctive diagnostic test for diabetic stiff hand syndrome: When you put your palms together in front of you, your fingers won’t fully touch each other because they can’t fully straighten.
What to do next: Treating hand cramps caused by diabetes typically starts with managing your blood sugar. Two important steps you can take to maintain better control of your blood sugar include:
Carpal tunnel syndrome typically causes pain and numbness in your hands, but it can also cause cramping.
Inflammation and swelling of the tendons in your wrist can compress the median nerve where your wrist meets your hand. This inflammation can lead to carpal tunnel syndrome.
Other symptoms, which often intensify at night, can include:
Risk factors for carpal tunnel syndrome include:
What to do next: If you have signs of carpal tunnel syndrome, check in with your healthcare team. They can diagnose carpal tunnel syndrome and recommend the right treatment, which may include:
Focal hand dystonia is a neurological disorder that causes spasms and cramping of your hand.
Experts believe this condition happens due to a dysfunction of the nerves that send signals between your brain and your muscles.
Initially, focal hand dystonia affects your coordination. As time goes on, you may also develop:
Note: Focal dystonia occurs most commonly in people between the ages of 40 and 60, and women develop it about three times as often. Your genes might also play a part, as about 10% of people with focal dystonia have a family history of the condition.
While focal hand dystonia can cause your hand to cramp or move involuntarily throughout the day, you’re more likely to experience something called task specific focal dystonia — cramping when performing activities that require fine motor control.
Types of task specific dystonias that can affect the hand include:
You may also experience task specific dystonia during other activities that require repetitive motion and fine motor control — for example, if you work as a hairstylist or shoemaker, or frequently type or use a computer mouse.
What to do next: Focal hand dystonia has no cure, but the right treatment can reduce spasms and cramping and help keep your symptoms from getting worse.
Treatments may include:
You might get hand cramps from time to time, especially if you’re doing a lot of fine movements in work or recreational activities. Usually, taking a break or changing your activities can provide some relief.
However, if you’re experiencing persistent hand cramps with no obvious cause, you might consider checking in with your doctor. They can evaluate you for any underlying medical cause and offer next steps to help relieve any pain or discomfort.
