DVT Calf Pain: What You Should Know

Deep vein thrombosis is a clot in a deep vein, often in the leg. The discomfort may feel like aching, cramping, heaviness, or tenderness in the calf. The leg can look swollen or feel warmer than the other side, but symptoms vary and some people have little pain. Calf pain also has many non-clot causes, including a muscle strain, bruise, or Achilles tendon problem; a symptom alone cannot identify the cause.

A clinician may assess both legs, ask about recent travel, reduced movement, surgery, illness, pregnancy, or previous clots, and arrange testing when appropriate. Do not try to diagnose a clot by rubbing the area or comparing pain by repeatedly walking on it.

Contact a medical service promptly if new, unexplained calf pain is accompanied by one-sided swelling, warmth, or tenderness. Explain when it began and whether it followed exercise or an injury. Until assessed, avoid strenuous exercise and avoid deep massage of the painful leg. Follow prescribed treatment exactly if a clinician confirms DVT; do not start or stop blood-thinning medicine without medical advice.

Call emergency services immediately for sudden breathlessness, chest pain, coughing blood, fainting, severe weakness, or a racing heartbeat with leg symptoms. These may indicate that a clot has travelled to the lungs. Even without chest symptoms, rapidly increasing swelling or severe leg pain warrants urgent assessment rather than waiting for a routine physiotherapy appointment.

Ask: Could this pain be a clot or an injury? Do I need an ultrasound or another test? Which activities are safe while I wait? What symptoms should make me seek emergency help? If treatment is prescribed, ask how to take it, what bleeding signs to watch for, and when follow-up is needed.
