Frequently Asked Questions

What does restless legs feel like during pregnancy?

It is typically described as a crawling, creeping, tingling, or itching sensation deep in the legs that creates an irresistible urge to move. It is relieved temporarily by moving.

When does RLS start in pregnancy?

It most commonly starts or worsens in the second and third trimesters, peaking around weeks 30–38.

Is pregnancy RLS caused by iron deficiency?

Iron deficiency is the most common and treatable cause. Getting a ferritin blood test and treating low iron has the best evidence for improving RLS in pregnancy.

Will RLS go away after I give birth?

In most cases, pregnancy-related RLS resolves within weeks to a few months after delivery. In some women it persists, especially if the underlying iron deficiency is not treated.
