How common is leg pain and swelling in pregnancy in deep vein thrombosis in pregnancy?

Leg Pain and Swelling in Pregnancy is a common presentation of Deep Vein Thrombosis in Pregnancy. A clot in a deep vein can obstruct blood flow and cause symptoms in one leg, although symptoms can vary.

Deep vein thrombosis, often called DVT, may cause swelling, aching, tenderness, warmth, or a feeling of tightness in the calf or thigh. The affected leg may look different from the other leg. Pregnancy itself can cause some ankle swelling and leg discomfort, so the pattern, timing, location, and examination matter. Symptoms can be mild, and some people have no obvious symptoms, which is why a new or one-sided change should not be self-diagnosed.

Contact your maternity team or an urgent medical service promptly about new one-sided leg pain or swelling. Explain when it began, whether it is worsening, and whether you have had recent reduced movement, surgery, a long journey, or a previous clot. A clinician may examine both legs and arrange imaging, commonly an ultrasound, if a clot needs checking. Do not massage a painful swollen leg or start medicines on your own. Keep your pregnancy details and current medicines available for the assessment.

Call emergency services immediately for sudden shortness of breath, chest pain, coughing blood, fainting, severe dizziness, or a fast or irregular heartbeat together with leg symptoms. These can signal that a clot has travelled to the lungs. Even without breathing symptoms, new one-sided swelling or pain in pregnancy warrants same-day clinical advice.

Could this be normal pregnancy swelling or does it need clot testing? Would an ultrasound be appropriate? What symptoms should send me to emergency care? If treatment is needed, how will it be managed during pregnancy and after birth?
