Although lymphedema tends to affect just one arm or leg, sometimes both arms or both legs may be swollen. Lymphedema is caused by a blockage in your lymphatic system, an important part of your immune and circulatory systems. The blockage prevents lymph fluid from draining well, and as the fluid builds up, the swelling continues. There's no cure for lymphedema, but it can be controlled. Controlling lymphedema involves diligent care of your affected limb. less

Less commonly, swollen lymph nodes are caused by cancer. Common areas where you might notice swollen lymph nodes include your neck, under your chin, in your armpits and in your groin. When your lymph nodes first swell, you might notice tender and painful lymph nodes, swollen lymph nodes that may be the size of a pea or kidney bean, or even larger. Treatment for lymphadenitis depends on the cause. In some cases, the passage of time and the use of over-the-counter (OTC) pain relievers and warm compresses may be all you need to treat swollen lymph nodes. For more serious cases, treatment of swollen lymph nodes involves treating the underlying cause. less
