What a compression wrap is doing

Compression wraps are layered bandages put on by a trained clinician to squeeze the lower leg gently. The pressure helps move fluid out of the leg, and it is a standard part of care for many venous leg ulcers and for leg swelling. Most compression wrap problems fall into a few groups: the wrap slips, it itches, it gets wet, or it feels too tight.

Compression is normally ordered only after the treating clinician has considered the blood flow into your leg, as our guide to circulation tests before compression explains.

What usually feels normal

  • A firm, snug feeling from the base of the toes to below the knee
  • Being more aware of the wrap for the first day or two
  • More comfort when you walk than when you stand still
  • A wrap that feels looser after a few days as swelling goes down
  • Toes that stay warm, keep their usual color, and move and feel as they normally do

Check your toes several times a day, and always before bed.

Signs a wrap may be too tight

Contact the treating clinician or the wound care team right away if you notice:

  • Toes that look blue, purple, gray or unusually pale, or feel cold
  • Numbness, tingling or a pins-and-needles feeling in the foot
  • New or worsening pain in the foot, toes, ankle or shin, or pain that wakes you
  • Toes that are newly swollen, or swelling bulging above the wrap near the knee
  • A wrap that has slid and bunched into a tight band

When the wrap is first applied, ask what to do if these signs appear and you cannot reach anyone. Most people are told to take the wrap off in that situation and then call. Write down the instructions you are given and follow them.

Call 911 for an emergency, such as a leg or foot that suddenly turns cold and white or blue with severe pain, chest pain, or sudden shortness of breath.

Slipping, bunching and loosening

A wrap applied to a swollen leg becomes loose as the swelling comes down. That means the compression is working, but a loose wrap can slide toward the ankle and gather into a ridge that presses hard in one place.

  • Do not pull a slipped wrap back up or wind it again yourself unless you were taught to. Uneven layers can press harder than the original wrap.
  • Call the care team and describe where it has moved. They may bring the next change forward.
  • Tell the clinician if slipping happens every time. The wrap type, padding or change schedule may need a second look.

Itching, heat and wet layers

Skin under a wrap can get dry, warm and itchy. Never push a knitting needle, ruler or anything else under the layers to scratch. It can break fragile skin that you cannot see. Tell the care team, and see our guide to itching around a healing wound.

Wet layers hold moisture against the skin and may not compress evenly. Call if the wrap gets soaked, if wound drainage comes through to the outside, or if you notice a new or strong odor. Our guide to showering with a wound dressing covers keeping a leg dry.

Habits that often make wraps easier to live with

Ask the treating clinician which of these fit your plan:

  1. Walking and moving your ankles through the day, since the calf muscle works with the wrap to move fluid.
  2. Raising your legs when you sit, and avoiding long periods of standing still.
  3. Wearing a roomy, adjustable shoe or the footwear you were given, so you stay steady on your feet.
  4. Keeping the top edge flat. Do not roll it down or tuck anything into it.

If swelling is a long-term issue, the clinician who manages your heart, kidney or circulation and vascular health should know how the leg is responding.

What to say when you call

Have these details ready:

  • When the wrap was put on and by whom
  • What you notice and when it started
  • The color, warmth and feeling of your toes compared with the other foot
  • Whether the wrap is wet, slipped or stained
  • Whether you have taken it off

Common questions

My wrap got wet. Can I dry it with a hair dryer?

No. A hair dryer warms the outside while inner layers stay damp against the skin, and heat can burn skin with reduced feeling. A soaked wrap usually needs to be replaced by someone trained to apply it. Call the care team and ask what to do until then.

Do I keep the wrap on while I sleep?

Follow the instructions for your specific product. Layered wraps applied by a clinician are usually meant to stay on day and night until the next scheduled change. Some other compression products are taken off at bedtime. If no one told you which kind you have, call and ask before changing anything.

My leg looks less swollen. Can I skip the next wrap change?

No. Less swelling is the goal, and it is also why wraps loosen and need to be reapplied on schedule. Stopping early often lets the fluid return. The treating clinician decides when the type of compression or the visit schedule changes.

Can I wear my regular shoes over a compression wrap?

Often a regular shoe will not fit over the layers, and forcing it adds pressure across the top of the foot. Ask the clinician what footwear to use. Many people wear a wider, adjustable shoe or one provided for this purpose.
