Blood clotting is an often dangerous condition that can kill if left unattended. Clots have received widespread media attention over the last couple of days, as health officials in several European countries suspended doses of the Oxford Covid vaccine after recipients developed them. While there is no established connection between the jab and the condition, understanding the symptoms could save lives.
What are the symptoms of a blood clot?
Blood clots are the colloquial name for a thrombus, which clog vessel valves.
These develop into dangerous medical conditions such as deep vein thrombosis (DVT) or a pulmonary embolism.
People need to make sure they catch any signs of a thrombus early on and receive the correct treatment.
The symptoms of a blood clot include the following in an arm or leg:
- Throbbing or cramping pain
- Swelling
- Redness or warmth
People may also experience these more general symptoms:
- Sudden breathlessness
- Sharp chest pains
- A cough
- Coughing up blood
Anyone who suspects they have a blood clot must call 111, as they can quickly become life-threatening.
One of the most dangerous conditions caused by blood clotting is a pulmonary embolism, which constitutes a medical emergency.
People who cannot breathe or notice someone has passed out must call 999 or visit A&E.
One-third of pulmonary embolism cases can kill, and immediately.

These include:

- Smoking
- Previous central line placement
- Immobility
- Oral contraceptives
- Pregnancy
- Obesity
