Ways to beat restless legs

Restless leg syndrome (Ekbom's syndrome)

If you feel an urge to keep moving your legs because of an uncomfortable, 'crawling' feeling, it's probably restless legs syndrome, RLS.
1 in 10 people get it, normally when resting. You may get sudden jerks of your legs too. It's thought an imbalance of brain chemicals may cause it.
Pregnant women and people with iron deficiency, diabetes, thyroid or kidney problems are prone to it. It eases if you stretch or massage your legs. Cutting out caffeine may help you're your symptoms, medication is also effective.

Restless legs syndrome causes uncomfortable feelings in your legs. As a result you have an urge to move your legs which gives temporary relief. Symptoms come on when resting and are worse at the end of the day. No treatment may be needed if symptoms are mild. Medication can ease symptoms if the condition is distressing.

What is restless legs syndrome and what are the symptoms?

Restless legs syndrome (RLS) is sometimes called Ekbom's syndrome after the doctor who first described it in 1945. It is a condition where you have an urge to move your legs. This is usually caused by an uncomfortable or unpleasant feeling in the legs. Many people with RLS find it difficult to describe the feeling - it may be like a 'crawling' sensation, or like an electric feeling, or 'like toothache', or 'like water running down your leg', or just uncomfortable or painful. The unpleasant feeling and urge to move occurs every 10-60 seconds and so you become quite restless.

The symptoms:

*develop when you are resting - particularly when you are sitting down or lying in bed. They tend to be worse if you are in a confined space such as in a cinema seat.

*are usually worse in the evening. In many cases they only occur in the evening, especially when trying to get to sleep. The symptoms can make it difficult to get to sleep. This can have a knock-on effect of causing poor sleep, and tiredness the next day.

*are eased briefly by moving, massaging or stretching the legs. Walking around will also ease the symptoms. However, the symptoms tend to return shortly after resting again.

usually affect both legs. Occasionally the arms are affected too.
Most people with RLS also have sudden jerks (involuntary movements) or legs when asleep. These can wake you up. The jerks may also occur when you are awake but resting.

Who gets restless legs syndrome?

A recent study suggested that up to 1 in 10 people develop some degree of RLS at some point in their life. It can affect anyone, and is slightly more common in women than men. The severity of symptoms can vary from a mild restlessness of the legs on some evenings, to a distressing problem on most evenings and nights which regularly disturbs sleep. This can lead to anxiety and depression on top of the RLS.

The cause is not known in most cases
This is called primary or 'idiopathic' RLS. This typically first develops in younger adults (under 45 years old). Symptoms tend to become slowly worse over the years. It is thought that the cause may be a slight lack of, or imbalance of, some brain chemicals (neurotransmitters), especially one called dopamine. It is not known why this should occur. There may be some genetic factor as primary RLS runs in some families. Caffeine or alcohol may make symptoms worse.

Secondary causes
Symptoms of RLS develop as a 'complication' of certain other conditions. For example:

Pregnancy. About 1 in 5 pregnant women develop RLS during pregnancy (especially in the later part of pregnancy). Symptoms often go after giving birth.
Lack of iron (iron deficiency) - which can cause anaemia. If this is the cause, then the symptoms of RLS usually go if you take iron tablets.
As a side-effect of some drugs. For example, it occurs in some people who take: antidepressants, antipsychotics, dopamine antagonists, antihistamines, calcium channel blockers, phenytoin, or steroids.
As a symptom of some other conditions. For example, kidney failure, Parkinson's disease, diabetes, and underactive thyroid.

How is restless legs syndrome diagnosed? - do I need any tests?

A doctor makes the diagnosis from the typical symptoms. There is no test to prove the diagnosis. A doctor may do some tests to rule out a 'secondary cause'. For example, a blood test to check for a lack of iron, and to rule out kidney failure.

What is the treatment for restless legs syndrome (Ekbom's syndrome)?

Treatment for secondary RLS is to treat the underlying cause such as iron deficiency, etc. However, most people with RLS have primary RLS.

Many people are reassured that they have primary RLS and not something more serious. (Some people with RLS fear that they have a serious neurological disorder.) Simply understanding about the nature of this condition may help to reduce anxiety about the condition. If symptoms are mild then no particular treatment may be needed or wanted. One or more of the following may be advised if the symptoms are troublesome.

Self help measures
One or more of the following may help

Simple distractions such as reading or watching TV may help if symptoms are mild.
Sleep hygiene to help improve your sleep patterns. This means:
Try to get in to a regular bedtime routine of going to bed and getting up at the same time each day.
Do not nap - especially in the evenings.
Take some exercise during the day (but not near bedtime).
Avoid drinks that contain caffeine (a stimulant) before bedtime.
Try to relax before going to bed. A relaxing warm bath may help.
A trial without caffeine or alcohol altogether. Reduce or cut out any drinks that contain caffeine such as tea, coffee and cola. Also limit, or cut out alcohol.

Try this for a couple of weeks or so to see if symptoms improve. If symptoms do improve, you could then experiment to see what level of caffeine or alcohol causes symptoms. For example, you may not need to cut these things out completely, but just take less than you were used to.

Consider your medication. If you think that a drug that you take may be causing the RLS, then see your doctor. Do not stop any prescribed drugs without discussion with a doctor who may be able to advise on alternatives.


  1. I had that while I was on chemo - drove me insane! I had to get up and walk around to make it go away...gone now though :o)

  2. Thanks for sharing this information. I had restless legs while pregnant and have been having a few odd occasions while on chemo. At least I know what I can try now. Thanks!

  3. I have had this issue for a while. I am not sure what to the on the RLS idea. But I don't like doctors and hate they come up with a name for everything. I blame mine on my RA and Lupus. So I take my meds and pottasium and seems to not have the issue as often as I use to.

    Thanks for visiting my blog and leaving a comment. Glad you like. Definatly feel free to check it out as you like. Stalk away! :-)

  4. I have had RLS for ever, on and off. I find that not eating late, and using relaxation techniques like yoga help. Moving about out of bed is good, too. Otherwise, as you say, massage and stretching work.

  5. Oh I am so glad I do not have RLS, that does not sound fun...

  6. I have had a mild version of this for a long time- usually bothers me at night. I find Kalms really help me ( herbal remedy)
