How daily exercise helps compression therapy
Your doctor or nurse may have told you about the importance of daily exercise to support your venous leg ulcer to heal. This is because exercises that improve ankle mobility, increase flexibility in your lower legs, and strengthen your calf muscles can all help improve blood flow to your legs and ankles.
Doing your exercises daily while wearing your compression therapy can make a difference. Movement improves blood circulation in your lower leg and reduces swelling, which enables the compression therapy to work more effectively.2
