Leg Cramps at Night: Tips to Reduce Discomfort (2024)

Nocturnal Leg Cramps vs. Restless Legs Syndrome

Nocturnal leg cramps are a distinct condition, but they are often misdiagnosed as restless legs syndrome (RLS) because both disorders involve uncomfortable sensations in the legs. Although symptoms are similar, there are some key differences between these disorders.

You may have nocturnal leg cramps Trusted Source National Library of Medicine, Biotech InformationThe National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.View Source if you are experiencing:

• Calf or foot cramps during the night
• Cramping that causes intense pain
• Sharp pain lasting less than 10 minutes
• Soreness lingering for hours or days
• Sleep disruption as a result of cramping
• Feeling distress around falling asleep

Even though restless legs syndrome also involves leg discomfort at night, its symptoms vary from those found in nocturnal leg cramps.

Other symptoms Trusted Source National Library of Medicine, Biotech InformationThe National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.View Source can include:

• Unpleasant or painful sensations in the legs
• Discomfort that worsens in the evening or night
• Relief found by walking or stretching
• Sensations that worsen with lack of exercise or rest

Symptoms of nocturnal leg cramps and RLS often present in similar ways. Therefore, nocturnal leg cramps might be difficult for your doctor to diagnose. To help your doctor figure out what issue is causing your leg discomfort, track your symptoms and bring detailed notes with you to your appointment.

Causes of Leg Cramps at Night

Leg cramps can be distressing and painful. Experiencing pain during the night can disrupt sleep. The exact causes of nocturnal leg cramps are unknown. However, there are some factors that may increase the chance of experiencing leg cramps during the night.

• Medications: Some medications, like diuretics, steroids, and antidepressants, are associated with nocturnal leg cramping. Talk to your doctor about any medications you are taking if you experience leg cramps during the night.
• Pregnancy: Leg cramps are a common experience in pregnant women, although some professionals consider pregnancy-related leg cramps different from nocturnal leg cramps. Researchers are unsure if this leg cramping occurs due to pregnancy itself, or because of a lack of blood flow in the veins as a result of pregnancy. Magnesium supplementation has been shown to reduce leg cramping in pregnancy, but you should talk to your doctor before beginning any new supplements.
• Dehydration: Not drinking enough water during the day can result in dehydration. Dehydration causes muscle weakness and cramping Trusted Source National Library of Medicine, Biotech InformationThe National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.View Source . Nocturnal leg cramps in particular are not associated with dehydration, but drinking water is still important. The exact amount of water you need to drink each day depends on your body weight, activity level, medications, and local climate.
• Standing for Extended Periods: Being on your feet for long periods of time can increase the risk of experiencing nocturnal leg cramps Trusted Source National Library of Medicine, Biotech InformationThe National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.View Source , making leg cramps a problem for people who must stand while they work. Taking breaks from standing and setting aside time to elevate your feet may help.
• Exercise: Exercising at the gym or through team sports may lead to muscle cramps. When muscles are fatigued or overworked Trusted Source National Library of Medicine, Biotech InformationThe National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.View Source , they can be more susceptible to cramping. Exercise-associated muscle cramps may be mistaken for nocturnal leg cramps when they occur at night. Stretching during an exercise-induced cramp has been shown to help relieve pain.
• Alcohol: Research of people over age 60 shows that those who drink alcohol are more likely to report Trusted Source National Library of Medicine, Biotech InformationThe National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.View Source nocturnal leg cramping. This cramping could be a result of alcohol’s ability to damage muscle fibers, but more research is needed.

How to Reduce Leg Cramps at Night

Although the exact cause of nocturnal leg cramps is unknown, there are ways to reduce the likelihood that you will experience them. Typically, leg cramps do not indicate a serious health problem. However, if you are experiencing frequent leg cramping, you should reach out to your doctor. You may be able to reduce the likelihood of experiencing leg cramps through:

• Hydration: Staying consistently hydrated throughout the day may help reduce the frequency of muscle cramps, since dehydration can cause cramps. Though some research suggests that nocturnal leg cramps are not caused by dehydration, it may help to drink water during long periods of outdoor activity or strenuous activity.

• Stretching: Doing some stretching or yoga before bed may help you reduce both the frequency and intensity of nocturnal leg cramps. Research suggests that engaging in a stretching routine Trusted Source National Library of Medicine, Biotech InformationThe National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.View Source before bed helps reduce cramps and leg pain after about six weeks. Nocturnal cramps usually do not last longer than 10 minutes, but stretching your calf or foot during the cramp may help relieve the pain faster.
• Baths: Some people claim that taking a bath Trusted Source National Library of Medicine, Biotech InformationThe National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.View Source helps relieve their nighttime cramps, though further research is needed. An epsom salt bath in particular could help reduce muscle pain Trusted Source National Library of Medicine, Biotech InformationThe National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.View Source . Epsom salt contains magnesium sulfate. An epsom salt bath could increase your magnesium levels, which may help relieve leg cramping.
• Massage: Massaging your calves or feet before bed may help you reduce cramping during the night by relaxing the muscles in your legs. If you have limited mobility, consider asking a partner to help.
• Heel Walking: Some people find that walking on their heels helps reduce nocturnal leg cramping. If you wake up in the middle of the night with a cramp in your calf, try getting up and walking on your heels.

In many cases, the cause of nocturnal leg cramps is unknown. Some leg cramps could indicate a more serious underlying disease, however, including:

• Cardiovascular disease
• Cirrhosis
• Kidney disease
• Osteoarthritis
