Why a healing wound itches

Itching during wound healing is one of the most common things people bring up at a wound care visit, and there are physical reasons for it.

As a wound heals, the body sends inflammatory cells to the area, and some of the chemicals they release, including histamine, trigger itch. New skin and scar tissue are tight and dry, and small nerve endings are regrowing. Our guide to how wounds heal explains the stages.

Other causes of itching around a wound

  • Dry skin. Common on the lower legs, in winter and in older adults.
  • Trapped moisture. Drainage or sweat held against the skin under a dressing.
  • A reaction to a product. Tape, adhesives, cleansers, creams or latex can cause an itchy rash, usually in the shape of whatever touched the skin.
  • Compression wraps. Warmth, sweat and dry skin under wraps often itch.
  • Skin changes from vein disease. Swollen legs with poor vein function can develop itchy, discolored, scaly skin. Our page on venous leg ulcers describes these skin changes.
  • Yeast or fungal rash. More likely in warm, damp places such as skin folds and between the toes.
  • Infection. Itching alone rarely means infection, but itching with new redness, warmth, pain or drainage should be checked.
  • Medications and health conditions. Some medicines cause itching, and so can kidney disease, liver disease and the dry skin that often comes with diabetes.

Several of these can be present at once. The treating clinician works out which ones apply to you.

When to mention itching to your clinician

Mention it at your next visit even if it seems minor. It may change which dressing or tape is used.

Call the office before the next visit if:

  • A rash, bumps, blisters or hives appear under or around the dressing
  • The itching began soon after a new dressing, tape, cream or medication
  • The skin is also more red or discolored, warm, swollen or painful
  • Drainage has increased or smells different
  • Itching under a compression wrap comes with numbness, tingling, new pain or toes that change color (call right away)
  • Scratching has broken the skin, or the itch keeps you awake

Call 911 for trouble breathing, swelling of the lips, tongue, face or throat, or widespread hives with dizziness. These can be signs of a serious allergic reaction.

What helps without harming the wound

Scratching does real damage. Fingernails carry bacteria, tear fragile new skin and loosen dressings.

  • Do not scratch the wound or scratch through the dressing.
  • Never slide a ruler, hanger or other object under a wrap, cast or boot.
  • Try gentle pressure with a flat hand over the dressing in place of scratching.
  • Keep the room cool, and wear loose, soft clothing over the area.
  • Keep nails short and smooth.
  • Ask before you use any anti-itch cream, lotion, ice pack or allergy medicine. Some products should not go near a wound, and some cause drowsiness that raises the risk of a fall.
  • Do not take off a dressing or wrap early to get at the itch unless your instructions say you may.

If compression seems to be the source, our guide to keeping compression wraps comfortable lists questions to ask.

What to write down before you call

A few notes help the clinician find the cause faster.

  1. Where the itch is: in the wound, at its edges, under the tape or over a wider area
  2. When it started, and what changed around then (a new dressing, tape, soap, laundry detergent or medication)
  3. When it is worst, such as at night or after a dressing change
  4. What the skin looks like, and what you have tried

Have your medication list ready, including anything bought over the counter. A medication review with your primary care clinician can look at whether a medicine is involved. Do not stop a prescribed medicine on your own because of itching. Call the prescriber.

How the care team may respond

Depending on the cause, the treating clinician may change the dressing or the adhesive, add a skin barrier, recommend a moisturizer for dry skin away from the wound, treat a rash or infection, or adjust the compression. Sometimes the answer is reassurance that the itch is part of healing.

When orders change, Gateway arranges the new supplies, as described on our page about dressing selection and changes. To ask about arranging wound care in Greater St. Louis or the Metro East, send the request care form or call 314-325-0126.

Common questions

Does itching mean my wound is healing?

Often it does, since the activity of repair and the tightness of new skin both cause itch. But itching is not proof of healing, and a wound can itch for other reasons. Clinicians judge healing by measurements, the look of the tissue and drainage over time.

Why does my wound itch more at night?

There is less to distract you, bedding adds warmth, and many people find that skin itches more in the evening. Tell your clinician if itching disturbs your sleep, because poor sleep makes recovery harder, and a change to the dressing or the skin care plan may help.

Can I be allergic to my dressing or tape?

Yes. Some people react to adhesives or to an ingredient in a dressing, cleanser or cream. The usual clue is an itchy, red or bumpy rash that matches the shape of the product on the skin. It can appear after weeks of using something without trouble. Tell the clinician, and keep a list of anything you have reacted to.

Is it normal for a closed wound or scar to itch?

It is common. New scar tissue is drier and less flexible than the skin it replaced, and it can itch for some time after the wound closes, especially after burns and skin grafts. Our guide to skin care after a wound heals has more. Report a healed area that reopens, blisters or becomes painful.
