why do my ankles swell
Swelling of the Ankles and Feet Symptoms and Causes. Swelling of the feet and ankles can occur as a result of conditions involving the local extremities as well as diseases and conditions that affect the entire body. Examples of causes of swelling of only one ankle or foot are sprains and strains.
Swelling of the foot, ankle and leg can be severe enough to leave an indentation, or pit, when you press on the area. This swelling (edema) is the result of excess fluid in your tissues â often caused by congestive heart failure or blockage in a leg vein.
