Dependent Rubor: Causes, Symptoms & What to Do

Red rash just above your ankles that only occurs when you retain water and your blood pressure is high could be a sign of dependent rubor. Dependent rubor is a skin condition that causes redness and swelling in the lower legs and feet. It is caused by the pooling of blood in the legs and feet when a person is standing or sitting for long periods of time. Dependent rubor is not usually a cause for concern, but it can be a sign of an underlying medical condition, such as heart failure, kidney disease, or liver disease. If you are experiencing dependent rubor, it is important to see a doctor to rule out any underlying medical conditions.
