Definition
By Mayo Clinic staffLymphedema refers to swelling that occurs most often in your arms or legs. It may affect just one arm or leg, but sometimes lymphedema can involve both arms or both legs.
The swelling occurs when a blockage in your lymphatic system prevents the lymph fluid in your arm or leg from draining adequately. As the fluid accumulates, the swelling continues.
No cure for lymphedema exists. But lymphedema can be controlled. Controlling lymphedema involves diligent care of your affected limb.
