Minor leg injuries could increase blood clot risk

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."
