Swelling following surgery is a normal part of the healing process, but in some cases it becomes persistent, problematic or develops into lymphoedema. Post-surgical swelling management through physiotherapy, compression and appropriate rehabilitation significantly reduces recovery time, prevents complications and supports return to normal function.
See therapies that may helpAcute post-surgical swelling is a normal inflammatory response to tissue trauma. It typically peaks at 48–72 hours after surgery and gradually resolves over days to weeks. Persistent post-surgical swelling beyond the expected timeline, or swelling that develops or worsens following the acute phase, warrants assessment.
Causes of persistent post-surgical swelling include: seroma formation (accumulation of serous fluid); haematoma; wound complications; deep vein thrombosis (requiring urgent medical assessment); and lymphoedema developing secondary to lymph node removal or damage (common following cancer surgery). The type and cause determine the appropriate management.
Post-surgical swelling concerns may present as:
Post-surgical swelling management:
Your surgical team should be the first contact for unexpected or worsening post-surgical swelling. Urgent medical assessment is needed for sudden calf swelling or pain (possible DVT), or if swelling is accompanied by fever (possible infection). A lymphoedema therapist is appropriate for persistent swelling with lymphatic features. A physiotherapist can guide appropriate graduated rehabilitation and swelling management.

Most acute post-surgical swelling reduces significantly within 2–4 weeks. Some residual swelling may persist for 3–6 months, gradually improving. Swelling that is not reducing as expected, worsening, or significantly impairing function beyond this timeline warrants assessment. The expected timeline varies significantly by procedure type and location.
A seroma is a collection of serous (clear) fluid that accumulates in a space created by surgery — commonly after mastectomy, wide local excision, hernia repair or abdominoplasty. It presents as a soft, fluctuant swelling and is typically managed with aspiration (drawing out the fluid with a needle) when symptomatic. Most seromas resolve with one or more aspirations.
Yes — deep vein thrombosis (DVT) is a potentially serious complication following surgery, particularly orthopaedic and lower limb procedures. Sudden onset of calf pain, tenderness and swelling following surgery should be assessed urgently. Standard post-operative DVT prophylaxis (anticoagulants, compression stockings, early mobilisation) significantly reduces risk.
General massage of post-surgical swelling is not always appropriate and can cause harm if applied incorrectly. Manual lymphatic drainage performed by a qualified lymphoedema therapist is safe and beneficial for post-surgical swelling with a lymphatic component. Ask your surgical team before applying any massage to a post-surgical area.
Physiotherapy addresses post-surgical swelling through: graduated exercise to stimulate lymphatic and venous return; specific movement programmes appropriate to the surgical procedure; scar mobilisation to prevent tethering; and guidance on activity pacing to prevent post-operative boom-bust cycles. Early physiotherapy involvement typically shortens recovery significantly.
