What is a Blood Clot?
This is the formation of a clot inside a blood vessel, usually in the leg, which may break off and go to lungs. This can be fatal.
Blood clots can be very serious – but there are effective treatments to deal with them and help prevent them
Signs and Symptoms of a Blood Clot
- Swelling or pain in one leg or arm
- Warmth or redness in the leg or arm
- Short of breath or rapid breathing
- Chest pain (particularly when breathing deeply)
- Coughing or coughing up blood
