  1. Unpleasant sensations wherein patients would describe it as either: cramping, creeping, tense, pulling, uncomfortable, itchy, burning, gnawing, aching, tingling and others
  2. The pain escalades when the patient is resting or about to rest

  4. The pain will be relieved if certain movements are done like jogging, walking, pacing, or whatever movements that offers relief
  5. Twitching of the legs during night time

Apart from that, by 2003, the NIH or National Institutes of Health made concise criteria on how to diagnose the problem with the symptoms presented like:

  1. Activity improvement where patients will find relief if they keep on moving
  2. Having the urge to move the limbs without sensation or with sensation
  3. It gets worse while at rest
  4. Worsening at night disrupting the circadian rhyth

Causes & Risk factors

There are 2 kinds of restless leg syndrome: the primary and secondary restless leg syndrome. In primary RLS, the cause is idiopathic or unknown. In secondary RLS however, there are underlying medical problems that causes the RLS


  1. Lack of iron or iron deficiency is said to be a cause of RLS. Iron is linked with the problem or at some point, it worsens the RLS
  2. Peripheral neuropathy. With this problem, the nerves in the arms and legs are damaged causing the lack of oxygen supply in the area then results to painful sensation, numbness and tingling sensation.
  3. Abnormalities in the neurotransmitters like dopamine are also likely to cause restless leg syndrome. These neurotransmitters help in regulating the muscle contraction or movements.
  4. Medications may also worsen the RLS like antiemtic drugs, antipsychotic drugs, anticonvulsants, anti-depressants, and even sudden withdrawal of benzodiazepines.

Treatment

As soon as restless leg syndrome is diagnosed, it is important to know the cause of the problem and address it right away. There are medications that can be taken in order to avoid worsening the problems like:

A. Opioids

These are narcotics which should be given at a small dose since it can be addicting. Opioids are analgesics of higher dose that helps relieve the uncomfortable feeling. Some opioids include codeine, oxycodone, etc.

B. Parkinson’s disease medications

The Parkinson’s disease medications are given in patients with RLS because it reduces their extra movements. Parkinson’s disease drugs such as carbidopa and levodopa increases the level of dopamine, one of the neurotransmitters in the brain that also causes the restless leg syndrome. Most of the time, the drug taken by patients with RLS are a combination of carbidopa and levodopa and patients are expected to feel mild side effects like nausea and fatigue.

C. Sleeping pills and muscle relaxants

These are prescribed since RLS has the tendency to disrupt the circarian rhythm which dictates the sleeping pattern of an individual. These drugs include clonazepam, eszopiclone, ramelteon, etc.

D. Epileptic drugs

Sometimes, drugs for epilepsy like gabapentin are prescribed to reduce abnormal twitching for patients with restless leg syndrome.

Home Remedies

Aside from the medications prescribed by the doctor, there are home remedies that need to be done in order to give relief from RLS. These include:

  1. Massage and warm bath are suggested in order to relax the muscles especially the legs. Aside from massage, there are also other relaxation methods like doing yoga, meditation especially at night before going to bed.
  2. Pain relievers are also suggested like NSAIDS to address simple discomforts and relieve muscle twitching sensations
  3. Having warm, clean and good sleep hygiene may promote sleep at night. As much as possible, it is important to have a cool and quite place and a comfortable bed to relax and entice sleep. Having a warm shower is also suggested to have good nights sleep.
  4. Application of warm and cold packs in alternate is helpful to reduce sensation of the limbs.

  2. I have a relative who died of cancer of the uterus. She was brought to the intensive care unit so that she will be monitored on a one on one basis. Every time the doctors would prescribe her medications, she will have to have some laboratory test done such as getting a complete blood count and the like. It was like this day in and day out. She had to laboratory test before and after the medications was given. Also, aside from that I have noticed that she was attached to an ECG monitor because according to her doctor she had irregularities with regards to her heart beat. Also she was attached to a positive pressure mechanical ventilator for she was having difficulty of breathing and also she manifested a loss of awareness and decrease in mental ability.
