Lymphedema refers to a condition in which excess fluid is collected in tissues and causes swelling due to blockage in the lymphatic system. It is commonly caused due to damage or removal of the lymph nodes as a part of cancer treatment. Sometimes lymphedema can be a congenital anomaly present at birth. Lymphedema often occurs in the upper extremities or lower extremities but can also occur in other areas like the face, neck, trunk, abdomen, and genitals. Along with the swelling, there can be a pain, numbness, tightness, and also infection.
