Once the cause has been identified and the wound has been cleaned, healing follows a long arc rather than a fixed schedule. Small superficial wounds may close in a few weeks. Deep wounds, wounds over bone, and wounds in limbs with limited blood supply can take months and often need surgery to close. The timeline below describes what commonly happens and in what order. Your own pace depends on the cause, your general health and how well the underlying problem is corrected, and your team will tell you where you sit.
Weeks two to four: the wound base changes
This is the phase where you find out whether treating the cause is working. In a wound that is responding, the base fills in with healthy red tissue known as granulation tissue, discharge reduces, the smell settles and the edges begin to creep inwards. Dressing intervals lengthen from daily to every second or third day. Compression for venous ulcers continues without interruption, and pressure relief for foot ulcers and pressure sores continues just as strictly.
If the wound looks the same at the end of week four, that is information rather than failure. It usually means something in the plan needs revisiting: blood supply, hidden infection in bone, pressure that is still falling on the area, blood sugar control, nutrition, or a diagnosis that needs rechecking with a biopsy. Ask for the plan to be reviewed rather than simply continued.
Weeks four to eight: deciding how the wound will close
Around this point a decision is made between letting the wound close on its own and closing it surgically. Shallow wounds with healthy granulation and good edges are often left to contract naturally. Larger areas, wounds over exposed tendon or bone, and wounds that have stalled despite everything being corrected are usually better closed with a skin graft or a flap.
A skin graft takes a thin layer of skin from another site, commonly the thigh, and lays it on the prepared wound. The graft is normally left undisturbed for several days before the first inspection, and the donor area is often the sorer of the two sites for the first week or so. A flap moves skin with its own blood supply, either from nearby or from elsewhere in the body using microsurgery, and involves a longer operation, a hospital stay and closer monitoring in the early days.
After either procedure the limb is usually rested and elevated, and weight bearing or movement is reintroduced gradually on your surgeon's instructions rather than by how you feel.
Weeks eight to twelve: new skin, but fragile skin
Newly healed skin and grafted skin are thinner and more delicate than the skin they replaced. They mark easily, tolerate friction poorly, tear with minor knocks and are sensitive to sun. Most people are advised to moisturise the area daily once the surface is fully closed, to protect it from pressure and rubbing, and to reintroduce activity in stages.
For leg ulcers, compression stockings usually continue long after the ulcer has closed, because stopping them is one of the commonest reasons ulcers return. For diabetic foot wounds, protective footwear and insoles are fitted and daily foot checks become a habit. For pressure sores, the seating and mattress arrangements stay in place, since the pressure that caused the sore has not gone away simply because the skin has closed.
Review visits usually become less frequent through this phase, moving from weekly to monthly as the area proves stable. Do not treat a longer gap as a discharge. If anything changes in between, such as a small blister, a crack, a patch of redness or a return of swelling, ask to be seen sooner. Photographs taken at home in the same light each time make it much easier for your team to judge whether an area is genuinely changing.
Three to six months: strength and scar maturation
Healed tissue continues to remodel for many months. Scars commonly look red, raised and firm for the first few months, then gradually soften and fade, though the final appearance varies widely between individuals and no scar disappears entirely. Itching and tightness are common during this period. Massage, moisturising, silicone products and pressure garments may be advised depending on the site and how the scar is behaving.
Return to work depends on the job. Desk based work is usually resumed much earlier, often once the wound is stable and comfortable, while standing work, walking long distances, driving and heavy manual labour take longer, particularly for lower limb wounds. Physiotherapy is often part of this phase where a joint has been stiff or a limb unused for weeks. Swelling that comes and goes through the day is normal for a while and usually responds to elevation and compression.
Six months and beyond: preventing the wound from returning
The wound closing is not the end of the story, because the condition that caused it usually remains. This is the part that decides whether you are back in a wound clinic next year. Keep blood sugar within the range your physician advises. Continue compression if you were told to. Keep using the footwear or cushion supplied. Check the skin daily if sensation is reduced, using a mirror for the sole of the foot. Stay off tobacco. Eat enough protein.
Report any new blister, crack, colour change or open area early rather than waiting to see whether it settles. A small area seen in the first week is usually a simple problem. The same area seen two months later can be a major one.
What can slow the timeline?
Common reasons for slower progress include limited arterial blood supply, infection in bone, continued pressure on the wound, poorly controlled diabetes, smoking, low protein intake, anaemia, some medicines including steroids, and a graft that does not take fully and needs repeating. None of these mean the wound cannot heal. They mean the plan needs adjusting, and this is exactly why regular review matters more than any particular dressing.
Contact your team promptly if a healed area breaks down again, if pain increases, if discharge or smell returns, or if you develop fever. Go to an emergency department instead of waiting if redness spreads rapidly, the skin turns dusky or black, or you feel very unwell.
