What You'll Learn
Causes of charley horses
Charley horses, also known as muscle spasms, can occur in any muscle in the body but are most common in the leg and foot. They are caused by muscles contracting involuntarily and then not relaxing, which results in pain and soreness that can last for hours or even days. While there is no definite cause for charley horses, they are more likely to occur due to the following reasons:
Overuse of the Muscle
Overusing or overworking the muscles is the most common cause of charley horses. Athletes, for instance, are at a greater risk of experiencing charley horses due to muscle fatigue or overuse. Charley horses in the upper leg are often associated with jumping or running, while those in the calf are linked to running or swimming.
Dehydration
Dehydration, especially during exercise, can trigger charley horses. Proper hydration can help prevent muscle cramps.
Electrolyte Imbalance
A lack of essential electrolytes like potassium and calcium can also cause charley horses. Consuming electrolytes through low-fat dairy products, bananas, lentils, spinach, and low-sugar sports beverages can help prevent muscle spasms.
Nerve Issues
In some cases, charley horses can be caused by nerve issues, such as a herniated disk irritating spinal nerves. An MRI scan can help determine nerve compression or irritation.
Medication
Certain medications can cause charley horses as a side effect by altering the body's electrolyte balance.
Medical Conditions
Several medical conditions can increase the risk of charley horses, including nerve damage, hardening of the arteries, spinal stenosis, thyroid disease, infections, and liver disease. Charley horses can also be a symptom of underlying health issues such as Lou Gehrig's disease (ALS).

Treatment options
Charley horses, or muscle cramps, are sudden, painful, involuntary muscle contractions that can occur in any muscle but usually affect the leg muscles. They are harmless and typically last only a few minutes, sometimes causing muscle soreness that lasts a few hours to a day. Charley horses can often be treated at home, but frequent charley horses may indicate an underlying problem that requires medical attention.
If you experience a charley horse, you can try the following at-home treatments to relax the muscle and ease the pain:
- Stretching and massaging the affected muscle
- Applying heat or ice to the area
- Taking a bath with Epsom salts
- Taking over-the-counter pain medication such as ibuprofen or naproxen
- Taking vitamin and mineral supplements like vitamin B12 complex, calcium, or magnesium (talk to your doctor before starting any new supplements)
Additionally, staying hydrated by drinking eight glasses of water per day and avoiding caffeine and alcohol can help prevent charley horses.
If you experience frequent charley horses, it is recommended that you consult a healthcare professional to determine the root cause and discuss further treatment options. Your doctor may recommend blood tests, muscle tests, nerve conduction studies, electromyography (EMG), or MRI exams to diagnose the issue. Depending on the cause, they may prescribe antispasm medication or muscle relaxants. In severe cases, physical therapy or surgery may be necessary to correct the underlying problem.

Prevention methods
Charley horses, or muscle spasms, can be prevented through a variety of methods. Here are some ways to reduce their occurrence:
Stretching and Exercise
Stretching the affected muscle can help alleviate the pain and prevent future charley horses. It is important to learn how to exercise properly, with the right training techniques, and to ensure adequate fluid intake to prevent spasms from occurring regularly.
Massage and Heat Treatment
Applying massage to the affected muscle can help relax it and reduce pain. Using a heating pad or taking a warm bath with Epsom salts can also relax the muscles and prevent spasms.
Medication and Supplements
Over-the-counter nonsteroidal anti-inflammatory medicines like ibuprofen or naproxen can help with pain relief. Additionally, taking vitamin B12 complex, calcium, or magnesium supplements may help prevent leg cramps. However, it is important to consult a doctor or healthcare provider before taking any new supplements or medications.
Addressing Underlying Conditions
Charley horses can be caused by underlying medical conditions, such as nerve irritation, peripheral nerve compression, or neurological changes. If you suspect an underlying condition, consult a doctor for a physical exam and potential further testing to determine the root cause. They may recommend antispasmodic medication or, in severe cases, physical therapy or surgery to correct the issue.
Lifestyle Factors
Reducing the frequency of charley horses can also be achieved by addressing certain lifestyle factors. Maintaining a healthy weight, staying hydrated, and ensuring adequate electrolyte intake can all help prevent muscle spasms. Additionally, reducing the consumption of stimulants like caffeine and reviewing any prescription medications that may be causing leg cramps are important considerations.
While charley horses are common and usually treatable, it is important to seek medical advice if they occur frequently or cause significant disruption to your life.

Risk factors
Charley horses, or muscle spasms, can occur in any muscle but typically affect the leg muscles. They are usually harmless and last only a few minutes, however, they can sometimes be prevented and treated. Charley horses can be caused by nerve irritation, muscle overuse, dehydration, electrolyte imbalances, or peripheral nerve compression.
Age
Older adults are more prone to muscle cramps, with 37% of people aged 60 and above experiencing leg cramps at night, also known as nocturnal leg syndrome.
Physical Activity
Athletes or individuals engaging in intense physical activities may experience charley horses more frequently due to muscle fatigue or overuse. Certain exercises or movements may be particularly associated with charley horses, such as running or jumping for upper leg cramps and running or swimming for calf cramps.
Weight
Being overweight is a risk factor for frequent charley horses. Weight gain during pregnancy, for example, can cause muscle cramps due to blood flow disruption and peripheral nerve compression.
Medical Conditions
Underlying medical conditions can increase the risk of charley horses. These may include neurological issues, dehydration, or electrolyte imbalances that occur during or after exercise. Additionally, individuals with irritated nerves, such as those with herniated discs, may experience muscle spasms in the back muscles.
Medication and Stimulants
The use of certain medications and stimulants, such as amphetamines and caffeine, can lead to an increased risk of charley horses. It is important to consult a doctor or pharmacist if muscle cramps occur after taking prescription drugs, as they may advise adjusting the medication.
