Symptoms and diagnosis
People describe a creepy-crawly, pulling, or itchy feeling deep in the legs with an urge to move. To diagnose RLS, the urge must (1) start or worsen at rest, (2) ease with movement, and (3) be worse in the evening or night. It's often mistaken for insomnia. Problems with brain iron and dopamine signaling are thought to play a role.
Causes and treatment
If your ferritin is low, iron supplementation under a doctor's guidance can help a lot (see iron-deficiency anemia). Pregnancy, kidney disease, and some antihistamines and antidepressants can worsen it. The 2024 AASM guideline favors gabapentinoids and IV iron, and advises against routine dopamine agonists because of augmentation, where symptoms get worse over time. Cutting caffeine and alcohol and keeping a regular sleep schedule help.
