10 Symptoms of a Sprained Ankle
Symptom #6: Discolored Skin
As mentioned above, the body will send white blood cells and fluids to the area and allow it to seep into the surrounding tissue. This causes swelling and it can also cause discoloration of the skin. This differs from bruising because it is not blood that has leaked from the blood vessels. Rather it is caused by proteins and fluids that have leaked from the surrounding blood vessels.
Skin discoloration in this way is not common and is a sign that you have caused significant damage internally. In instances where permanent damage might have occurred, it would be wise to seek advice from a medical professional.
