Lymphedema Rehabilitation Beyond Compression Garments

Lymphedema is swelling caused by lymph fluid that cannot drain. Lymph is a clear fluid that carries white blood cells through a network of thin vessels and small nodes. Surgery that removes lymph nodes, and radiation that scars them, can break that drainage path. Fluid then pools under the skin. It shows up most often in an arm or a leg, but it can also affect the breast, chest, neck, face, belly, or genitals.

A sleeve or stocking is only one piece of the standard care. The full treatment is called complete decongestive therapy, or CDT. The National Cancer Institute describes four parts: skin and wound care, manual lymphatic drainage (a gentle massage that helps move lymph fluid through the body), exercise, and compression. Many people are handed a garment and nothing else. That is one common reason swelling does not improve.

CDT runs in two stages.

Phase one is the reduction phase. Skin and wound care, exercise, manual lymphatic drainage, and compression bandaging are done daily, for an average of about 15 days. The compression here is short-stretch bandaging, which is layers of low-stretch wrap rather than a garment you pull on.

Phase two is maintenance. You switch to a fitted compression garment. You keep up the skin care and the exercise. Manual lymphatic drainage continues as needed. Phase two has no end date. Knowing that at the start makes the plan easier to live with.

Garment type matters. Flat-knit garments give a more even pressure and suit stage II and stage III swelling. Stretchy elastic garments are better suited to stage I, or to stage II once CDT has brought the limb down.

The National Cancer Institute describes this care as delivered by a certified lymphedema therapist, or CLT. It defines a CLT as "a physical or occupational therapist trained to treat lymphedema." Nurses often teach garment use.

The strongest credential is CLT-LANA. That means the therapist has finished at least 135 hours of training and passed a board exam from the Lymphology Association of North America. The Lymphatic Education and Research Network keeps directories of LANA-certified therapists and of approved training schools. Ask whether the person treating you holds that credential, or is working toward it.

Ask which method your clinic uses, and ask for the numbers.

• Tape measure. A difference of 2 cm or more at any point, compared with the other arm, is treated by many experts as meaningful.
• Water displacement. A difference of 200 mL or more between the two arms is a common cutoff.
• Perometry. An infrared scanner estimates limb volume without touching you.
• Bioimpedance spectroscopy. A small current measures how much fluid sits in the tissue.
• Imaging. Ultrasound, MRI, CT, and lymphoscintigraphy can find where the flow is blocked.

Staging runs from 0 to III. In stage I, pressing the swollen area leaves a pit, or dent, in the skin. By stage III, the skin feels hard and thick. The stage guides which garment and which treatment fit.

For years people were told to protect the arm by not using it. That advice has shifted. The National Cancer Institute calls exercise "a natural pump for the lymph system" that can improve the flow of lymph.

One prevention trial followed women after breast cancer surgery. Its main measure was an arm volume increase of more than 5 percent at one year. Among women who had five or more lymph nodes removed, 22 percent of the control group met that measure, against 7 percent of the group doing a slowly increased weight-lifting program. Worth knowing alongside it: rates of clinician-diagnosed lymphedema were much lower in both groups and did not differ between them. Ask a therapist to build the progression rather than guessing at it.

Bacteria enter through small breaks in the skin, and swollen tissue clears them poorly. The result is cellulitis, a skin infection that can move fast.

Practical steps from the National Cancer Institute: wear gloves when cooking and gardening, use lotion so the skin does not dry and crack, put antibacterial ointment on cuts, and avoid extreme heat and strong sun. Blood pressure readings and blood draws should use the arm without swelling.

A pneumatic compression pump squeezes the limb on and off through an inflatable sleeve. It can keep fluid moving. The open questions are the right pressure, the right schedule, and whether it needs to continue long term. There is also a concern that pressures above 60 mm Hg, used over a long period, may injure lymph vessels. Have a therapist set the pressure and the timing rather than adjusting the dial yourself.

Three procedures are used at specialized centers.

• Lymphaticovenous anastomosis, or LVA, connects blocked lymph vessels to nearby small veins. It is usually offered for earlier-stage swelling.
• Vascularized lymph node transfer moves healthy lymph nodes, with their blood supply, into the affected area. In one comparison, limb size and cellulitis episodes improved more with this than with LVA.
• Liposuction removes the fatty tissue that builds up in a long-swollen limb. In one study, average excess arm volume fell from 1,607 mL to below the size of the other arm, and skin infection attacks dropped from 0.47 to 0.06 per year.

Two useful questions for a surgeon: how many of these do you do a year, and what does compression look like afterward?

This changed recently, and many people were given the old answer.

Since January 1, 2024, Medicare Part B covers lymphedema compression treatment items. Section 4133 of the Consolidated Appropriations Act, 2023 created the benefit. Covered items include standard and custom-fitted gradient compression garments, gradient compression wraps with adjustable straps, and compression bandaging supplies.

You need a lymphedema diagnosis and an order from your doctor or other provider. After the Part B deductible, you pay 20 percent of the Medicare-approved amount. The limits are three daytime garments per affected body part every six months, and two nighttime garments per affected body part every two years. Medicare allows extra replacements if items are lost, stolen, damaged beyond repair, or if your limb changes size.

The National Cancer Institute says to call right away if you have a fever or other signs of cellulitis. Those signs are:

• Pain, tenderness, redness, or swelling in the affected area.
• Skin that feels warm to the touch.
• Fever.

Contact your doctor promptly, though not as an emergency, for new heaviness, tightness, fullness, swelling, numbness, or tingling in an area treated with surgery or radiation. Early swelling is easier to reduce than late swelling.

If the swelling involves the head or neck, the team also wants to hear about trouble speaking, eating, or swallowing, and about changes in voice, vision, or hearing. New trouble breathing is an emergency. Call 911.
