High cholesterol is the name given to having too much of a fatty substance in your blood. This substance, known as cholesterol, can lead to blockages in your blood vessels.
Blocked blood vessels raises the risk of heart attacks and strokes, as it limits the blood supply to the heart and the rest of the body.

It's not always easy to know whether you have high cholesterol, as there aren't any obvious symptoms.
But, you may be at risk of the condition if you develop a subtle pain when you walk.
Some people with high cholesterol find that they have an unusual pain while they're walking.
This pain may be caused by arteries becoming blocked, which reduces blood flow to the legs.
The blockage may be caused by a build-up of cholesterol, which inhibits the blood supply to the extremities.
If you develop an unexplained pain while you're walking, you should consider speaking to a doctor.
