How do I know if I have edema?
Your doctor can tell whether you have edema by examining you. The skin over the swollen area may be stretched and shiny. Pushing gently on the swollen area for about 15 seconds will leave a dimple. If this happens, your doctor might want to do some tests to see what is causing your edema.
