Minor leg injuries, such as muscle and ligament tears, sprained ankles and even bruises, may raise the risk of blood clots. After studying about 6,000 patients, researchers found that those who suffered a blood clot were three times as likely to have also had a recent minor leg injury.
Researchers speculate that leg injuries may do some damage blood vessels. The injury could also limit a person's mobility, and sitting still for long periods of time has also been linked to blood clots.
There's more on this study is in this week's "Archives of Internal Medicine."
