An abnormal build up of fluids (predominantly water) in the legs is known as oedema. Leg swelling is known as “lower extremity oedema” and may affect one leg or both legs equally. The swelling is painless and is a common problem, especially among older people. The most common symptom of oedema includes the swelling of the affected area, which also causes the surrounding area to tighten and indentation may also take place when pressure is applied to the affected area with a finger, sock or shoe. Other symptoms may include blurry vision, dizziness, mild headache, a sudden increase in weight, tender limbs, skin discoloration or redness in an extremity (cellulitis or DVT), jaundice, abdominal pain, nausea, and vomiting.
