It is mainly associated with psychological malfunction rather than neurological malfunction. Hence should be helpful by consulting a psychiatrist first.

My restless leg was caused by my multiple sclerosis medication. I stopped the medication and the restless leg symptoms are gone.

Dear Taku, Welcome to HealthcareMagic,
Restless leg syndrome (RLS) is currently considered a neurologic movement disorder of the limbs, often associated with a sleep complaint. Once correctly diagnosed, RLS can usually be treated effectively and in some secondary cases, it can even be cured. Though exact pathogenesis is unclear, the most widely accepted mechanism involves a genetic component along with abnormalities in the central, subcortical dopamine pathways in brain. A number of drugs are used for treatment depending on symptoms.
