Lymphedema is, to put very simply, a chronic swelling. It happens when there is damage or blockage of the lymph nodes, making it difficult for lymphatic fluid to drain properly.
There are a number of causes of lymphedema, including parasitic infection, injury or trauma, radiation therapy, surgery, tumors, and skin infections. It is common for women who have been treated for breast cancer to develop lymphedema in their arms.
Unfortunately, there is no cure for lymphedema. However, there are many treatment options to help manage it, such as compression garments and pumps, manual lymph drainage massages (MLD), and range-of-motion exercises. Lymphedema can be progressive or lead to complications, so it’s very important to keep up care!!
