Compression Garments & Sleeves for Lymphedema

A compression sleeve is not a bandage for an injury. It is a working part of your treatment, and it does its job only while you are wearing it.

The National Cancer Institute describes lymphedema as "swelling caused by a buildup of lymph fluid in the body between the skin and muscle." Cancer and its treatment can disrupt how that fluid moves in three ways: a tumor can block the flow, surgery can disrupt it, or "radiation therapy causes scar tissue that blocks the flow of lymph fluid."

The fluid does not stop being produced when its usual route is blocked. It pools. Compression provides outside pressure that helps keep it moving instead of collecting.

NCI lists "short stretch bandaging, compression wraps, leggings, or stockings" among the ways to move fluid and prevent buildup. Which one you use depends on where the swelling is and what stage of treatment you are in — bandaging is often used to bring swelling down, and a fitted garment to hold the gain.

There is also a compression pump, which NCI describes as "a device connected to a compression sleeve or sock that applies pressure intermittently to the arm or leg."

This is the part worth being firm about. NCI's guidance is that "your nurse or CLT will help you find garments that fit properly and will show you how to use them."

A CLT is "a certified lymphedema therapist, a physical or occupational therapist trained to treat lymphedema." They manage your treatment options and show you home techniques, including manual lymph drainage you can do yourself.

NCI does not publish do-it-yourself measurements, a compression strength to ask for, or a schedule for replacing worn garments. Those are decisions the source deliberately routes through a trained person, and that is a reasonable signal about how much fit matters here. A sleeve bought online without measurement may be too loose to help or tight in the wrong places.

NCI's instruction is specific: "Wear compression garments daily when you are up and moving around and at night as advised by your CLT."

Two parts to that. Daytime wear is tied to being upright and active, when gravity works against you. Night wear is not automatic — it depends on what your CLT advises, and night garments are often different from day garments.

Compression is one piece of complete decongestive therapy, which also includes manual lymphatic drainage — NCI describes this as "gentle massage that helps move lymph fluid through the body" — plus bandaging, exercise, and skin care, all managed by a CLT.

NCI's home management list includes:

• Exercise. "Exercise is a natural pump for the lymph system."
• Elevation. Raise the affected limb above heart level when resting.
• Weight. "Stay at or get to a healthy weight."
• Water. "Drinking plenty of water will help keep lymph fluid moving."
• Salt. "Reduce salt in your diet."
• Clothing. Wear loose clothing and avoid tight bands.

That last point is not a contradiction of wearing compression. A prescribed garment applies graduated pressure by design; a tight watch strap, sock band, or sleeve cuff creates a pressure point that pinches flow.

Skin that is stretched and swollen is easier to break, and broken skin lets bacteria in. NCI's advice: "Wear gloves when cooking and gardening to protect your hands from injury. Use lotion to prevent dry skin and cracks where bacteria can enter."

Cellulitis is a potentially serious bacterial infection, and NCI is direct about it. The signs are "pain, tenderness, redness, and swelling in the affected area," skin that is warm in the swollen area, and fever.

• Call your care team the same day if you have a fever or other signs of cellulitis. NCI's wording leaves no room for waiting: "If you have a fever or other signs of cellulitis, call your doctor right away."
• Treat the fever as an emergency instead if you are on chemotherapy. CDC says so plainly: telephone your team the moment the temperature reaches 100.4°F (38°C), day or night, and go to an emergency department if they cannot be reached quickly.
• Call your care team the same day if you see redness or other signs of infection in the skin under or around the garment. NCI says to report those promptly.
• Call your care team within a day or two if you notice heaviness, swelling, tightness, numbness, tingling, skin discoloration, hardening, or difficulty moving the affected area. These can be early signs, and early signs are the ones worth catching.

NCI suggests asking your doctor about lymphedema risk, including: "Will I be monitored for early symptoms?"

Others worth adding: Who is the certified lymphedema therapist I should be referred to? How do I know when this garment no longer fits? What should I do if it becomes uncomfortable or leaves marks?
