Restless legs when sick

Restless Legs is a pattern of uncomfortable leg sensations and an urge to move. It may occur alongside Restless Legs Syndrome, but an episode during an illness does not prove a particular diagnosis. Iron deficiency, kidney disease, and peripheral nerve problems can contribute in some people. A clinician can separate a familiar pattern from signs of infection, circulation trouble, or another acute problem.

Rest, drink fluids if you have been told they are suitable, and move your ankles or walk gently when safe. Use warmth or massage for comfort and keep your sleep area calm. Make a list of medicines started or stopped during the illness and show it to a clinician. Do not add iron or a sedating treatment without checking for interactions and whether it is appropriate for you.

Contact a clinician promptly if symptoms continue after the illness improves, prevent sleep, or follow a new medicine. Seek urgent help for severe weakness, confusion, fainting, chest pain, sudden breathlessness, or a single swollen and painful leg. Fever with a rapidly red or painful leg also needs prompt assessment.

Ask whether the illness or its treatment could be affecting your legs, whether your usual medicines should change, and whether blood tests are needed. Explain your fluid intake, sleep disruption, and any new swelling, numbness, or weakness.
