Lymphedema: What to Know About Swelling and Treatment
September 23, 2026
Swelling in an arm or leg can happen for many reasons. But if the swelling does not go away, does not improve when you elevate the area or begins making everyday activities more difficult, it may be a sign of lymphedema.
Lymphedema is a long-term condition, but specialized therapy can help manage swelling, improve movement and make daily activities more comfortable.
What Is Lymphedema?
Lymphedema occurs when lymph fluid builds up in the body’s tissues. It most often affects an arm or leg, although it can develop in other parts of the body.
The condition is especially common among people who have had lymph nodes removed or damaged during cancer surgery or radiation treatment. It can also develop after an injury or infection or in people with circulation problems, limited mobility or obesity.
What Are the Signs of Lymphedema?
Lymphedema often develops gradually. Signs may include:
Swelling that does not go away
A feeling of heaviness, fullness or tightness
Difficulty moving the affected arm or leg
Clothing, shoes or jewelry that feel tighter than usual
Skin that becomes thick, firm or discolored
Clear or yellow fluid leaking through small openings in the skin
Talk with your healthcare provider if you notice persistent swelling or other changes. Lymphedema is generally easier to manage when treatment begins early. Sudden swelling, especially when accompanied by pain, redness or warmth, should be evaluated promptly because it may have another cause.
How Is Lymphedema Treated?
Lymphedema therapy can help reduce swelling, improve movement and lower the risk of complications. Because every patient’s needs are different, a therapist will develop a treatment plan based on your symptoms, health and daily activities.
Treatment may include:
Gentle massage techniques that help move lymph fluid
Compression bandages or garments
Exercises that support movement and fluid flow
Skin care to help prevent irritation and infection
Education for managing symptoms at home
Your therapist may also help connect you with compression garments or other equipment based on your individual needs.
How Can Presbyterian Help?
Presbyterian’s specialized therapists work with patients and caregivers to make lymphedema care part of everyday life. They can help you understand the condition, learn techniques to manage symptoms and find practical ways to remain active and independent.
Having access to therapy within your region may also reduce the time and distance you need to travel for ongoing appointments.
If swelling is affecting your comfort, movement or daily routine, talk with your healthcare provider about whether lymphedema therapy may be right for you. With the right treatment and support, many people can manage their symptoms and continue doing the things that matter to them.

The clinical framing also aligns with the National Cancer Institute’s lymphedema guidance, particularly its emphasis on early evaluation, common symptoms and personalized therapy.
