Lower Limb Lymphedema
Lower limb lymphedema accounts for the most cases of lymphedema (80%) It can be seen at any age and in approximately 65% of cases, the lymphedema is unilateral. It is found in both men and women. The typical pattern of involvement is that lymphedema is initially seen in the distal part of the leg (towards the feet) and extends proximally over time. Symptoms usually begin with painless swelling but there may be a sensation of heaviness or fullness in the leg particularly in hot weather or at the end of the day. As with upper limb lymphedema, the swelling is initially pitted and skin is soft but over time the subcutaneous tissue becomes fibrotic resulting in no pitting when pressure is applied. The spread of the edema usually takes place in the first year, though enlargement of the limb can continue if treatment is not initiated. The progression of symptoms is similar to upper limb lymphedema.
