Blood clot: Three signs in your legs include new pain swelling or warm discoloured skin

Stop the Clot says: “The first and most important thing you can do to protect yourself from a life-threatening blood clot is to learn if you are at risk.”

It says some of the most common risk factors for blood clots are hospitalisation, major surgery, pregnancy, and sitting too long, especially with legs crossed.

Similarly, if you have an inflammatory condition such as Crohn’s disease or rheumatoid arthritis, this can increase your risk of clots.

There are some steps you can take to reduce your risk. For example, the NHS says you should drink plenty of water to avoid dehydration, as you’re more likely to get a clot if you’re dehydrated.
