Nocturnal Leg Cramps: Night-time Calf Muscle Pain

Nocturnal leg cramps can lead to a rude awakening: You're suddenly sleepless and in pain in the middle of the night. Symptoms of nocturnal leg cramps include excruciating contractions of the calf muscles, and sometimes of the foot muscles as well.

Nocturnal leg cramps are true cramps and not spasms. The muscle remains in a cramped and contracted position, which accounts for the intensity of the pain. If you touch the affected calf, you may be surprised to discover that your muscles feel very hard, almost like concrete, a measure of the power of the cramp.

Studies have shown increased electrical activity in the affected muscles, but doctors still don't know what causes nocturnal leg cramps. In some cases, it may be a fluid imbalance or a vitamin deficiency.

Treatment for leg cramps is straightforward and easy to follow. Avoid tight bed covers, which can lead to pointing of the toes and subsequent cramps. Stretch your calf muscles for about five minutes nightly before getting into bed. If you have a cramp, pull your toes back (don't point them), and, if necessary, put your foot on the floor and lean forward.

Some evidence suggests that a potassium deficiency may cause nocturnal leg cramps. Many sleepers have eliminated their cramps entirely just by making sure they eat plenty of potassium rich foods, including

  • Bananas, apricots, nectarines, dates, grapes, or raisins
  • Beans
  • Cabbage/broccoli family of vegetables
  • Oranges, grapefruit, and their juice
  • Pork and lamb
  • Potatoes and corn
  • Saltwater fish (for example, tuna)
  • Tomatoes and tomato juice

Of course, if you wake up with a leg cramp, a banana's not going to do you much good, so here are some tips to relieve cramps immediately:

  • Apply a hot compress to the cramped muscles.
  • Massage the cramped muscles.
  • Stretch and flex. Lie on your back in bed, lift your legs, extend them toward the ceiling, and then point your toes to the ceiling and flex them slowly back toward your calf. Repeat this flex and stretch until the cramps stop. For an extra good stretch, grab your toes while still in this position and pull them down toward your knees. You'll feel this stretch working in the back of the calf muscles.

Other studies have linked cramps to dehydration. Staying adequately hydrated at all times is a good idea for many reasons, so add preventing nocturnal leg cramps to the list. Finally, pregnant women, dieters, people taking diuretics, (medications that increase the amount of urine you produce) and people who've experienced a bout with vomiting and diarrhea may also experience leg cramps because their calcium and phosphorus levels get out of whack. If you fall into any one of these categories and you have a bout of nocturnal leg cramps, consult with your doctor for the best course of treatment.

    Standing on a cold floor cures it for me. The muscles are sore afterwards though.

    Sometimes the cramps are so painful you cant even lean forward to grab your toes to pull back, sort of like a electrical shock you end up straightening out your body. My remedy is to just fly out of bed no matter how bad it hurts to step on the floor and lean forwards.

    This happens to me when I run/workout a lot. I chalk it up to dehyrdated with low levels of potassum, magnesium, calcium and sodium. The cramps are often severe, like being stabbed in the calf. I have to jump out of bed, stand up and lean forward. They will go away quickly. I do feel a muscle tightness afterwords. To keep them at bay I try to get in a lot of stretching, replace fluids and eat a banana and something salty after working out, if I slip up, they come back.

    I found that if I eat bananas even cooked in something I am guaranteed to have leg cramps at night. Does anyone know what causes this? It seems totally backwards to everything I read.

    I always get these after I have been drinking alcohol. It's like a formula for me: drinking alcohol = charley horse

    I just started putting bananas in my morning smoothie (I don't like to eat them in general) and last night I had a horrific calf cramp (first time ever). Anyone have any ideas?

    I have been getting leg cramps for years but for the last 3 weeks I have been getting them every morning and this morning was the worse. I had a severe cramp at my upper thigh to my groin also on the calf of my other leg. I applied hot compressors to no avail and took 3 let cramp pills with quinine under the tongue and pain subsided within minutes, purchased over the counter.

    I've found that magnesium supplements can be helpful for tight muscles .

    I had cramps in both legs that occured at the same time... started at the ankle, pain at the shin and up to the knee along with pain at the back of my thighs. I hurt so bad I broke out in a sweat... walked around for about 5 minutes, I could not stand up straight. What in the world???? This is the second time it's happened! I'm almost 50 and try to take a B complex vitaman daily along with eating bananas.... Painful!

    Hi, I usually get these like once a year which is making me feel better after reading your comments. I get them at night or in the evening doesn't really matter. It hurts SOOOOO MUCH jezuz they should use it as a torture device :(. Anyhow i usually juss stay still and massage the area. I'm too afraid to get up and stand on it. It just hurts so much.

    I get these cramps pretty often and I can feel my muscles start to tighten so I start to walk on it before it gets really bad. I've found that if you put pressure on it you will get instant relief as in standing on it or walking around. Also when I eat a bananna it usually accures that night so I don't know if you have to eat just enough of the bananna or what.

    my night and morning calf cramps are always relieved fastest by letting the calf finish cramping, massaging it very gently while trying to wiggle the toes of that leg. Then standing and walking help keep it from cramping again. I never stretch a cramp since I've heard it can tear muscle fibers.

    I didn't know these cramps were so common, I've woken up screaming several times from them. I get them mostly when i take afternoon naps though. I just try to get myself standing and pull my toes back.

    Now you can all laugh. Several years ago I had leg cramps almost every night and hd to get uop and sgtretch or rub ASpercreme on the calves of my legs. I mentioned it to a cousin from Texas and she suggested I put a bar of ivory soap under the bottom sheet at the bottom of the bed. I did it and except for the one or two times over the past several years that the bar of soap was dislodged and pushed down the side of the mattress I have not had any leg cramps. Give it a try, It only costs a bar of Ivory soap.

    Another use for Ivory soap. I once used a bar of Ivory soap to make an emergency repair on a leaky gas tank in my truck. It got me through the day. An epoxy mix was a more permanent solution. True story. When my legs cramp while in bed I quickly get up and just walk until the muscle relaxes. Messaging the area also helps.

    My leg and feet (mainly feet) cramps are awful. Happens as I begin to relax at night - significantly more constant as I go to bed. Massaging, stretching, stalks of bananas, and soap do not work. The only relief, I find is eating lots of salt - even drinking straight pickle juice. Now - I know this can't be good for you but that's the only way I get relief. Have gotten in hot hot bath which sometimes helps. Looking to treat cause more than treat symptom. HELP!

    I get calf cramps at least every 3 months at nigt. I drink about 10 glasses of water each day, I eat one banana each day, I walk about 3 miles each day, I stretch my calf muscles almost every night. Several years ago I was getting them quite often, now they come only 3-4 times per year. My doctor ran a bettery of tests a couple of years ago and told me eveything was fine - and he has no clue why I keep getting these. Last night I got another one -- this one was probably the most painful one I've had and lasted about 3-5 minutes - I stretched my leg hard and bent my toes toward my knee and that helped. I have never tried to stand up while I am hurting (I am afraid I'll hurt more if I stand up) -- But I will try that next time. Thanks for sharing your experiences.

    I have found that the surest way to relieve leg cramps is to stand immediately. If the cramp is below the knee in the calf or foot I flatten my foot on the floor by putting my weight on that leg. If in the thigh, I bend forward from the waist (as far forward as necessary}. This never causes an increase in pain and relieves the tightness immediately and gently. It ALWAYS works. I would love to find as sure a way to prevent them.

    I find myself getting these cramps 1-3 times per night. They have to be the most painful and uncomfortable things i've ever been through. I hate going to sleep at night cause i know i'm just going to wake up in a couple hours to my leg feeling like the muscle is being stretched to the point of ripping. I have not tried any remedy to prevent, or even stop them when they occur. From what i've read, eating bananas and drinking plenty of water before going to bed is not the best solution. My calves are always sore throughout the day and i just really need to find some kind of solution to this problem. Also, i share a room with my brother, and we have a bunk bed and i sleep on the top. I would consider putting pressure on my feet by standing, but unfortunately getting down is nearly impossible.

    I used to get these nocturnal leg cramps in my calves and feet quite often when I ran in high school. And I started getting them again when I got back to running this year. I usually just grab my calf and wait for the pain to go away, probably not the best idea. The soreness afterwards is annoying though. I'm thinking it might help to do some running stretches , especially the ones focusing on the calves.

    I have gotten cramps on the front, back, ankle, and feet at the same time in the middle of the night. Sometimes along with the thighs. I have recently started taking Vitamin D capsules with the Potassium tablets I have been taking previously. It seems to been decreasing the frequency of the cramps. Good luck! Aloha, Grant

    My leg cramps are becoming more frequent. I'm almost certain they are linked to inactivity. Very seldom will one wake me out of a dead sleep, but they're usually triggered when I move suddenly and try to stretch after I've been sleep for a while. I usually hop up really quickly, but then I get suddenly very tired and want to lay down. But I don't dare cause that makes the cramp worse. Problem is the long the cramp goes on, I start to get very sick to my stomach and want to throw up. Then I have to go to the bathroom and have trouble holding it. If that's not enough, I actually fainted once and woke up on the floor. But hey, my leg had stopped hurting by then. So now, I just make myself lay on the floor, try to stretch my legs out, roll around and scream until the pain goes away. This is starting to happen more and more frequently. Stretching does seem to help...I think. I hadn't stretched in two days and I've had bad cramps two nights straight I've had these horrible cramps. I guess I'll have to keep stretching every night and hopefully that will reduce the incidence of these awful cramps.

    I wake up every night with horrific foot & leg cramps. The doctors do not seem to have an answer. After checking blood levels and everything is in within normal range, they are stumped. I was taking 325mg of Quinine for years and having no cramps at all They have taken this off of the market replacing it with Ropinole or Generic (Requip). I have tried various over the counter meds that have no effect at all. I am up at least 4-7 times every night. With so many people of all ages afflicked with these painful cramps...you would think that someone would run an extensive study on the cause. JHC r

    Leg cramps can be caused by a change of the heel height of shoes. It does not have to be a dramatic change of height, so you men are also included, although women are more likely to have extreme differences in heel heights. Note that the heel height of your dress shoes and whatever you usually wear, or your exercise shoes, may be different, which causes exercise of different muscles in the calf. Also even a small heel is different than walking around in sock feet or barefoot at home all evening. If you are having calf cramps in the night, try wearing the same shoes daily, and in the pm for a while to see if that helps you. If it does, you may need to exercise more for the musculature of both the calf and the feet (which of course won't stop leg pain overnight!), or just wear always the same heel height by buying and wearing slippers with the same heel height you wear during the day around the house instead of socks or barefoot.

    Woke to a double header (both calfes) this morning. Thought about having my legs taken off at the knees, but decided it would make it too hard to get around during the day!

    my leg cramps come from a long basketball practice and just sneak up on me during the night

    I have suffered from frightful leg and groin cramps for 50 years or more and all that time took quinine tablets. Recent hospital admissions necessitated listing all medications and the registrar condemned quinine as eventually disrupting (or some medical term) platelets in the blood and I should ditch it in favour of magnesium tablets, which I have done. I still get cramps from time to time and live in fear of the next episode. I have an infrared lamp permanently available for relief and a pad I can heat in the microwave if I can get that far. Also,I am very suspicious of fortified wines and NEVER EVER touch sherry. Am surprised at the comments about bananas as I thought they were good fellas.

    i have a leg cramp like once a month but usually its triggered by inactivity and then sudden movement. fastest solution is to get up and stand on the feet that is cramping or just put pressure on that feet. usually it goes away in a matter of seconds when i do that. i guess i'm a light sleeper because i wake up as i feel a cramp coming so its only a little sore and i go right back to sleep.

    I used to get leg and foot cramps at night; a very painful experience. So I started to think if I was eating anything new, and indeed, I realized that I had taken to drinking grape juice every night. I checked the internet and discovered that grape juice is high in potassium, which is a good thing, but in excess can produce muscle spasms and cramps. I stopped drinking grape juice every night and gradually but surely, the cramps disappeared. I am so relieved that I wanted to share this with other sufferers. This might not be every one’s case, but there could be someone out there who could benefit from this testimony.

    One solution that no one has written about is to use compression stockings. Granted, they may not look very chic when one is wearing shorts, but I rarely get leg cramps anymore. Check with a vascular specialist.

    I have just begun getting these horrible calf cramps in the past month and they are increasing in both intensity and activity (nearly nightly) now. So I am a newbie. However, something I have been doing for years, for ANY kind of cramp, comes from an old wive's tale and I promise it works for me every time. So, LOL again, but here it is: pinch the skin between your upper lip and nose together with your forefinger and thumb and hold until the pain subsides. It is usually fairly quick. Good luck to you all and happy sleeping!:)

    Early Friday morning, I was awakened by a cramp in my left calf. I got up and walked it off. I went back to sleep, and when I woke up to start my day, I noticed my right leg hurt whenever I walked. It's weird because a day later, I still have pain. It hurts to touch my right calf, but it doesn't feel swollen. I don't know if anyone has any suggestions on what I should do. I've tried stretching my calf, which hurts to do, but usually works. I've also increased my water intake.
  33. Posted by Jack
    Patella Knee Cap, I have the exact same thing. I started getting cramp in my right calf a few weeks ago every night and throughout the day, my right calf hurt constantly. Once the cramps died down then so did the permanent pain in my calf in the day. Now they are back and my calf is hurting constantly again. I'm not sure of a solution for either problem yet though. I'm thinking about seeing a doctor.

    I've been getting carmps in my calf every night. I finally decided to make a Dr appt for next week. One of my co-workers overheard me and gave the same suggestion as I read above: pinch the skin between your nose and lip with your forefinger and thumb.... Sounds crazy but that's two people, so I'm going to try it.

    I too have been getting leg cramps lately at night, and like the rest of you....wake up in pain. For me it only happens when I pass out on the couch...but not everytime of course, about 1-2 times a month. For me, I have to chalk it up to dehydration. I am horrible at drinking water....always go straight to the diet coke, beer, or juice (pretty much anything with flavor)...I know....it is a bad habbit. My sure fire instant releif has been quit the opposite from everyone else. When I wake up from the cramp pain, I get up and lay on the floor on my stomach....weird, but it works and it's better than sleeping with a bar of ivory soap...lol
