Calf pain after a C-section: what you need to know

Pregnancy, the weeks after birth, reduced movement and surgery can all make a clot in a deep leg vein more likely. Deep vein thrombosis may present with pain or tenderness in one calf, swelling on one side, warmth, redness or a heavy feeling. Muscle strain, cramp and fluid-related swelling can also cause discomfort, but symptoms alone cannot reliably separate these causes. Do not massage a painful or swollen calf while waiting for assessment.

Contact your maternity unit, obstetric clinician or an urgent-care service the same day and describe when the pain began, whether it affects one leg, and whether swelling, heat or colour change is present. A clinician may examine both legs and arrange an ultrasound if a clot is suspected. Until you receive advice, avoid strenuous activity and do not delay care to see whether stretching settles the pain.

Call emergency services immediately for sudden shortness of breath, chest pain, coughing blood, fainting, severe dizziness or a very fast heartbeat. These can occur if a clot travels to the lungs. Seek urgent assessment for rapidly increasing leg swelling, marked colour change, severe pain, or a foot that becomes cold, pale, numb or weak. The red-flag symptoms themselves determine the urgency.

Ask whether your symptoms require a leg ultrasound, what activity is appropriate while the cause is being assessed, and which changes should send you directly to emergency care. Also mention previous blood clots, a known clotting condition, current medicines, fever, wound problems and any recent period of limited mobility, because these details can change the assessment.
