Lymphoedema is characterized by the excessive accumulation of fluid and proteins in tissues due to lymphatic system dysfunction, commonly presenting in the extremities with symptoms like heaviness, pain, and mobility limitations. It can be primary or secondary, and its management includes Complete Decongestive Therapy (CDT), which incorporates manual lymphatic drainage, compression therapy, exercise, and skin care. Effective self-management and education are critical for patients to minimize the risks of worsening lymphedema and associated complications.
