Oedema (Swelling) – peripheral oedema is an abnormal amount of fluid retention below the skin in the foot ankle or leg and can be caused by systemic diseases, pregnancy in some women, either directly or as a result of heart failure, or local conditions such as varicose veins, thrombophlebitis, insect bites, and dermatitis. Lymphodema is another type of oedema that is due to an insufficient lymphatic system.
Localised swelling in the foot ankle or leg can result from an acute injuries including breaks or soft tissue damage, or inflammation, arthritis or post surgery.
Chronic swelling can require the use of compression stockings. Your podiatrist can help diagnose and help manage this condition depending on the cause and what further tests may be required.
