Here, your limbs, most likely your legs, move (for example, they might jerk, twitch or, in the case of your feet, flex upwards) about every 20 to 40 seconds. This repetitive movement can last a few minutes or several hours. While the disorder on its own is not a serious medical condition, it can contribute to chronic insomnia or lead to daytime fatigue. Sometimes it can be a symptom of a serious condition that needs to be treated, such as diabetes or kidney disease.
If the disorder occurs together with restless leg syndrome, or if it causes significant insomnia or daytime fatigue that impacts on your life, you may be given medication. This will either reduce your movements or help you sleep through them.
