Learning Activity
Why do some people experience leg pain when walking?
Sore muscles can hurt when you walk, but pain can also be a symptom of poor circulation.
If you are out of condition and try to walk quickly, you may feel pain and discomfort in your legs as you stretch muscles that are not used to being stretched.
If you have diabetes or other cardiovascular risk factors such as high blood pressure, your doctor should evaluate leg pain associated with walking. You may have intermittent claudication or poor blood flow.
