Although the exact cause of restlesss leg syndrome (RLS) is unknown, it has been associated with obesity, pregnancy, smoking, iron-deficiency anemia, peripheral neuropathy, heavy metal toxicity and other toxins, endocrine disorders, renal failure, caffeine and alcohol use, and certain medications, particularly H2 blockers and some antidepressants. A hereditary basis has also been suggested. RLS is characterized by an uncontrollable need to move the limbs, especially during times of rest and relaxation. Other symptoms attributed to RLS include leg tingling, itching, burning, or aching in the legs (and sometimes arms). Other conditions that may mimic RLS include Parkinson's disease, neuropathic or circulatory conditions, muscle diseases, or joint conditions. Eliminating tobacco and alcohol and adding exercise to your routine can help alleviate symptoms.
