What is Lymphedema?

Your lymphatic system [link word to page] is made up of tiny vessels and lymph nodes that help move fluid and support your immune system.

When these vessels or nodes are:

• removed
• injured
• blocked
• or not formed correctly

…the fluid can’t drain properly. Over time, it collects in the tissues and causes swelling.

When lymphatic fluid stays in the tissues, it can:

• cause visible swelling, also known as edema
• make the area feel heavy or tight
• slow down healthy blood flow
• make wounds heal more slowly
• increase the risk of infection, such as cellulitis

Lymphedema tends to progress if it’s not treated – but with early care [link word to page], it can be managed very effectively.

Physical Signs You Might Notice:

• Swelling in an arm, leg, or body area where lymph nodes were removed or damaged
• Swelling that starts slowly and gradually increases over time
• One limb looking or feeling larger than the other
• Swelling that comes and goes at first, but becomes more constant
• Skin or tissue that feels firmer, thicker, or leaves an indentation when pressed

What People Often Report Feeling:

• A sense of heaviness, aching, or fullness in the limb or body area
• Light tingling or unusual sensations in the affected area
• Clothing or shoes that feel tighter or no longer fit the same
• Jewelry that’s harder to put on or feels snug
• Swelling that was there but seems to have gone away
• Swelling that comes and goes regularly

Not all swelling is lymphedema.
Swelling from heart, kidney, or vein problems affects the whole body.
Lymphedema affects specific areas where the lymphatic system is not working properly.

There are two main types:

• Primary lymphedema
• Secondary lymphedema
