Chronic oedema is swelling or puffiness in the ankles or legs which has lasted for more than 3 months. The swelling does not improve when you put your legs up. The skin may feel harder and thicker
There are many causes, but a common one is sitting still for long periods of time. The medical term is ‘dependency oedema’. Another cause is ‘lymphovenous disease’ - poor circulation in the veins back to your heart. A condition called ‘lymphoedema’ can cause swelling anywhere in the body. Lymphoedema occurs when the lymphatic system is not working properly.
As legs can swell for a range of reasons - see your nurse or GP, who will diagnose the cause and give appropriate advice.
