Restless leg syndrome is diagnosed by a doctor
after a patient describes symptoms that are consistent with the diagnosis. There are no blood tests, x-rays, CT scans, or MRIs or any other test that can diagnose restless leg syndrome (RLS). RLS is a syndrome where the affected person gets a sudden irresistible urge to move ones leg while they are lying down trying to sleep.
This urge to move the leg causes one to continuously change sleeping positions as the leg is moved. RLS is thus a cause of sleep deprivation, as people that suffer from it have a hard time falling asleep. This is why we take the symptoms very seriously and prescribe medication when its appropriate. The leg tapping you are describing does not sound like RLS.
I recommend that you schedule an appointment with your primary care physician
. He or she can take a more detailed history of your symptoms and perform a thorough physical exam. If your symptoms are consistent with RLS, then your doctor may decide to give you a medication for it. If it isn't, but your symptoms of leg tapping are still bothering you, then you and your doctor can discuss ways to help your problem. Good luck.
