Leg swelling needs the right protocol
One-sided swelling may need DVT ultrasound. Chronic heaviness or ankle swelling may need venous reflux mapping. Cold foot, weak pulses, or walking pain may need arterial assessment. The correct pathway depends on the symptom and risk factors.
When not to wait for a clinic booking
Shortness of breath, chest pain, fainting, severe sudden swelling, stroke-like symptoms, or a cold painful foot should be treated as urgent medical problems and assessed through emergency care.
