What Does Leg Pain and Swelling in Pregnancy Feel Like With Deep Vein Thrombosis?

Symptoms may include swelling, aching, cramping, heaviness, warmth, or tenderness in one leg, often involving the calf or thigh.

The affected leg may look larger than the other leg, feel tight, or become sore when standing or walking. The skin can feel warmer or appear redder, though visible skin changes are not always present. Normal pregnancy can also cause leg discomfort and swelling, so the pattern, examination, and medical testing are needed to tell causes apart.

Contact your maternity team or urgent medical service promptly if you have new one-sided swelling, pain, warmth, or tenderness. Do not massage the painful leg or delay assessment to see whether it settles. Keep a note of when symptoms began, which leg is affected, and whether you have breathlessness or chest symptoms.

Call emergency services immediately for sudden shortness of breath, chest pain, coughing blood, fainting, severe dizziness, or a racing heartbeat with breathing difficulty. These symptoms can signal that a clot has affected the lungs and need emergency assessment during pregnancy or after birth.

Ask whether your symptoms need same-day assessment, which tests are suitable during pregnancy, and which warning signs should prompt emergency help. Ask how to move safely while awaiting evaluation and whether any medicines or compression support are appropriate for you.
