Why Restless Leg Syndrome is a Problem
Restless leg syndrome (RLS) is a nervous system disorder that causes discomfort in your legs (and other extremities) during the night, and may affect up to 10% of the U.S. population [WebMD]. By “discomfort”, we mean that RLS usually is uncomfortable enough that it interferes with your sleep.
The primary problem associated with restless leg syndrome is sleep deprivation because it causes you to wake up and move your leg to ease the discomfort. It’s kind of a vicious cycle, as the sleep deprivation may in turn also worsen your symptoms.
Indirectly, another risk for people with mild or intermittent RLS is that it will go undetected or misdiagnosed. The problem here may be mild but chronic sleep deprivation.
Treating Restless Leg Syndrome
Unfortunately, the causes of RLS are relatively unknown, and in consequence there are no direct treatment for it. That being said, we know that there are things you can do that may significantly decrease your chances of getting RLS, the frequency with which you get it, or the severity of your RLS.
Some treatments used in mild to moderate cases of RLS are targeted at lifestyle changes such as:
- Beginning regular exercise
- Developing good sleeping patterns/habits
- Reducing the use of stimulants
- Reducing the consumption of alcohol and tobacco
Non-lifestyle treatment methods include:
- Leg massages
- Hot baths and/or ice packs
- A vibrating pad
In some cases drugs may be used, but the effects may relieve or worsen your RLS (results are sporadic) and the effectiveness may lessen over time.
What Causes RLS
As said, the causes of restless leg syndrome are unknown - for many people it’s “just one of those things” - though science has illuminated some pertinent information and risk factors for developing RLS.
Some factors that influence the severity or onset of RLS are:
- Genes are thought to play a role (nearly half of people with RLS have a family member who also has it).
- Certain diseases include symptoms of RLS, such as anemia, Parkinson’s, and diabetes
- Some medications, such as antinausea drugs or antipsychotic drugs, may make RLS symptoms worse
- Pregnancy (especially in last trimester) may trigger symtoms
- Sleep deprivation may trigger symptoms
- Affects both sexes but is more common in women
- May begin at any age (even in young children), but people who are severely affected are generally middle aged or older
In some cases, like RLS onset during pregnancy or after sleep deprivation, RLS may go away naturally. In other cases, RLS may be a chronic problem without treatment.
Symptoms of RLS

- May come and go
- May be chronic
- May be intermittent
When the discomfort is enough to keep you up or wake you up, it is considered a sleeping disorder. Some of the symptoms include feeling the following on your legs at night:
- Aching, throbbing, or burning
- Cramping (especially in calves)
- Buzzing or vibrating feelings
- Itchy feeling
- Feeling of pins and needles
- Creepy crawly feeling
- Irresistible urge to move your leg to relieve the discomfort
The good news about RLS symptoms is that, as long as they are not mild, they are often easy to identify – i.e., it’s hard to miss an irresistible urge to relieve leg discomfort. If you notice these symptoms and live in Anchorage, you can consult with us or your healthcare provider to begin the road to treatment.
