  • Family history - People whose family members have had RLS are more likely to develop it. Thus, genetics may contribute to the improper utilization or lack of iron in the brain that causes RLS.
  • Nerve Damage - in the legs/feet or sometimes in the arms/hands may cause or worsen RLS. Other conditions that can cause nerve damage, including diabetes.
  • Medication - that may cause RLS, include Antinausea medicines (for stomach upset treatment), Antidepressants, Antipsychotics (for mental health disorders), Antihistamines (for Cold and allergy), and Calcium channel blockers (for heart problems and high blood pressure).
