What to expect from a GP consultation for deep vein thrombosis

The GP may ask when swelling, pain, warmth or skin colour change began, whether it affects one leg, and whether symptoms followed surgery, injury, reduced movement, a long journey, pregnancy or hormone treatment. They may ask about previous clots, cancer, bleeding problems and medicines. The examination compares both legs and checks swelling, tenderness, skin changes, pulse and general condition. A DVT cannot be confirmed from symptoms alone, so the GP may arrange urgent ultrasound or direct you to an emergency service for assessment.

Tell the practice immediately that you have new one-sided leg swelling or pain and follow instructions about where to be assessed. Bring your medicines, relevant medical history and details of recent travel, surgery or reduced movement. Do not massage a swollen painful leg or take someone else's anticoagulant. If treatment is started, take it exactly as prescribed and report unusual bleeding or a severe reaction.

Call emergency services immediately for sudden breathlessness, chest pain that worsens with breathing, coughing blood, collapse or severe dizziness. These can indicate that a clot has travelled to the lungs. Do not drive yourself if you have these symptoms. A new painful swollen leg also needs prompt assessment even when breathing is normal.

Ask where testing will happen, whether you should avoid travel or strenuous activity while waiting, what symptoms require emergency help, and how any anticoagulant would interact with your other medicines. Confirm when results and follow-up will be communicated.
