If the following happens, call 999 or go to the emergency department:
You have symptoms of deep vein clot formation, such as pain and swelling, and:
- Breathing difficulty
- Chest pain
Deep vein clot formation can be very serious because the blood clot in your veins can break, flow through the blood and get stuck in the lungs. This is called lung blockage.
Lung blockage can be life-threatening and requires immediate treatment.
