Leg cramps at night causes, remedies, difference from restless leg syndrome

Leg cramps at night – nocturnal leg cramps – are pains that occur during the sleeping hours. They can cause a person to wake up and occur at night due to prolonged hours of inactivity. Nocturnal leg cramps commonly occur in the calf but can also cause pain in the thighs and feet. Pain due to leg cramps at night can last for mere seconds or for several minutes. After the pain passes, muscle soreness may linger for the rest of the night or even until the following day. Both men and women can experience cramps in leg and they occur more commonly in adults over the age of 50.

Leg cramps at night, different from restless leg syndrome

Both nocturnal leg cramps and restless leg syndrome (RLS) occur during sleeping hours but that is the only similarity between the two conditions. There are many differences between leg cramps at night and restless leg syndrome, including:

RLS does not cause pain or cramping, while nocturnal leg cramps do.
RLS is more of a discomfort or crawling feeling in your legs.
RLS causes the desire to move the legs, while nocturnal leg cramps often prevent movement.
Moving the leg in RLS offers relief – moving the leg in nocturnal leg cramps does not, instead stretching is required.

Causes and risk factors of leg cramps at night

The exact cause of nocturnal leg cramps is often unknown, but potential causes and risk factors include:

Sitting for prolonged periods of time
Over-exertion of the muscles in the leg
Standing or working on concrete floors
Sitting improperly

Medical conditions, too, can contribute to nocturnal leg cramps, such as:

Pregnancy
Alcoholism
Dehydration
Parkinson’s disease
Neuromuscular disorders
Structural disorders like flat feet
Endocrine disorders like diabetes
Diuretics, statins, beta agonists

Treatment and prevention for nocturnal leg cramps

Treatment depends on the cause. For example, if the cause of your nocturnal leg cramps is due to dehydration, ensure you stay well hydrated throughout the day. Other treatment and preventative methods for leg cramps at night include:

Use horse chestnut, which has been shown to increase blood flow to the legs.
Take a relaxing, warm bath prior to sleep to ease any muscle tightness.
Apply a heating pad to the affected area.
Try acupuncture treatment to loosen tight leg muscles.
Ensure you are not deficient in magnesium or potassium – deficiencies in both minerals are linked to muscle cramping.
Stretch your legs prior to bed.
Partake in water exercises to build leg muscles.
Wear ergonomic shoes and avoid high heels.

What to do when cramps occur

When a nocturnal muscle cramp strikes it can nearly leave you paralyzed. Knowing how to properly handle an attack will offer you relief and leave you less sore afterwards. Here are some tips to better handle nocturnal leg cramps.

While sitting on the floor extend both legs out in front of you. Now flex your feet at the ankles and point your toes toward your knees – you may want to tug on your feet to offer an even better stretch.
Get up slowly and walk around a bit – shaking your legs can also improve blood flow.
Gently massage the area in a circular motion.
Ensure blankets and sheets are not tight enough to make the leg muscle contract.
Take a tablespoon of yellow mustard to relieve discomfort.
