How a closed incision heals

A surgeon closes an incision with stitches, staples, skin glue or adhesive strips so the edges stay together while the body bridges the gap. If you are wondering about surgical incision healing and what to expect, the short answer is slow, steady improvement. The surface seals first, and the deeper layers gain strength gradually after that.

The pace depends on the operation, the part of the body and your health, so your surgeon is the best source for timing. Our guide to how wounds heal explains the stages.

What is usually normal

  • A thin pink or red line right along the incision, with mild swelling
  • Soreness that eases a little from day to day
  • A small amount of clear or light pink fluid early on
  • Bruising that changes color as it fades
  • Itching, tightness or a pulling feeling
  • Numbness or tingling in the skin nearby
  • A firm ridge under the incision line, where new tissue is forming

The direction matters most. A healing incision looks and feels a little better over time, not worse.

Changes that need a call to the surgeon

Call the surgeon’s office, or the on-call number after hours, if you notice:

  • Redness that spreads away from the incision, or red streaks
  • Pain, swelling or warmth that increases after it had been improving
  • Thick, cloudy, yellow or green drainage, or a bad smell
  • Drainage that increases or soaks the dressing
  • Fever or chills
  • Edges that pull apart, or a stitch or staple that comes loose early
  • A sudden gush of pink or clear fluid, especially from an abdominal incision
  • A new bulge near the incision
  • A rash or blisters under the tape or dressing

Several of these are signs of wound infection. If the incision separates, our guide on when a surgical wound opens covers the first steps.

Call 911 for bleeding that does not stop with firm pressure, an incision that opens widely, chest pain, trouble breathing, fainting or confusion. Calf pain with swelling in one leg after surgery also needs urgent attention, because it can mean a blood clot.

Questions to ask before you leave the hospital

  • When may the first dressing come off, and does the incision need a cover after that?
  • When may I shower, and when may I soak in a tub or pool?
  • Will the stitches dissolve? If not, who removes the stitches or staples, and when?
  • Should glue or adhesive strips be left to come off on their own?
  • What are my limits on lifting, driving, stairs and exercise?
  • Which number do I call after hours?
  • When is my follow-up visit, and who checks the incision before then?

Keep the answers with your discharge papers.

Daily habits that protect the incision

  • Wash your hands before and after touching the incision or dressing
  • Look at the incision once a day in good light, with a mirror or a helper for places you cannot see
  • Follow the dressing instructions exactly, and ask before using any ointment, cream, peroxide or alcohol
  • Hold a pillow firmly against a chest or belly incision when you cough, sneeze or laugh
  • Keep to lifting and activity limits even when you feel well
  • Leave scabs, glue and strips alone
  • Eat enough protein, drink fluids and avoid tobacco

Who is more likely to have healing problems

Diabetes, smoking, extra body weight, poor nutrition, weak circulation, steroid or immune-suppressing medicines and emergency surgery are all linked with slower healing and more infections. If any apply to you, ask whether your incision should be checked sooner or more often.

Do not change a medicine on your own. A primary care visit after discharge is a good time to review blood sugar, new prescriptions and nutrition.

How Gateway supports follow-up after surgery

Your surgeon’s instructions always come first. When an incision needs more attention than a routine recheck, Gateway arranges wound follow-up after hospital discharge with partner clinicians who see people at home, in rehabilitation centers and in skilled nursing across Greater St. Louis and the Metro East.

We request the discharge instructions and operative note, schedule visits, arrange ordered supplies and keep the surgeon’s office informed. Read more about post-surgical wounds, call 314-325-0126, or request care online with a name and phone number.

Common questions

What is the hard ridge I feel under my incision?

A firm ridge directly under the incision line is usually new tissue knitting the deeper layers together, and it tends to soften and flatten with time. Mention it at follow-up so the surgeon can confirm. Call sooner if the area becomes more painful, red or warm, feels like a soft pocket of fluid, or bulges when you cough or stand.

Why is the skin around my incision numb?

Small nerves in the skin are cut during surgery, so a numb or tingling patch near the incision is common. Feeling often returns slowly, and a small area may stay different. Numb skin cannot warn you of heat, cold or rubbing, so be careful with heating pads, ice packs and tight waistbands. Report numbness that spreads or comes with weakness.

Should I put antibiotic ointment on my incision?

Only if your surgeon told you to. Many incisions are meant to stay clean and dry, and ointment can loosen skin glue and adhesive strips before they are ready to come off. Some people also get a rash from these products. If the incision looks dry or crusted and you are tempted to treat it, call the surgical office and ask what they want used.

My staples are out. Is the incision fully healed?

Not yet. Removal means the surface has sealed well enough to hold without them. The deeper layers keep gaining strength for a long time afterward, which is why lifting and activity limits often continue past that visit. Ask what you may do now, what should wait, and whether any strips placed after removal should be left to fall off.
