How to Fix a Deep Wound in Project Zomboid (Build 42, 2026)
Short answer: open the Health panel (H) and read the body part before you touch it. If it also says Lodged Glass Shards or Lodged Bullet, take that out first, because the game will not even offer you the Stitch option while glass is in the wound. Then disinfect if you can, stitch with a Suture Needle or Needle + Thread, and bandage on top. A deep wound can heal on bandages alone, but it takes about a month of in-game time, so stitching is the treatment you want.
A deep wound is more severe than a laceration. It bleeds heavily, keeps draining health while it is untreated, and a bandage over it goes dirty within seconds. You get one from smashing a window with bare hands, climbing through a broken window, walking over broken glass without shoes, falling down a level, crashing a vehicle at around 40 to 50 mph, taking an axe hit, and, importantly, from pulling a lodged bullet or glass shard out of yourself. That last one is why the order of operations below matters.
First: is something still in the wound?
The Health panel lists Lodged Glass Shards and Lodged Bullet as their own entries, separate from the deep wound. They are not cosmetic labels:
- Glass blocks stitching outright. The Stitch option is not shown on a body part that still has glass in it. If you cannot find the option, this is almost always why.
- Glass comes out with tweezers, forceps, or bare hands. Bare hands work, but they cost you: the action takes twice as long and adds a further 30 pain on top of the normal cost.
- A bullet needs a tool. Tweezers or forceps only, there is no bare-hands option, and it is the single most painful first aid action in the game.
- A bandage hides the problem. The panel only shows the lodged glass or bullet line while the body part is unbandaged. Slap a bandage on in a panic and the foreign object silently stops being displayed while it keeps bleeding you.
- Removing it can give you the deep wound. Pulling out a shard or a bullet is itself a listed cause of a deep wound, so expect to stitch afterwards rather than being surprised by it.
What You Need
- Tweezers or Forceps, for glass and bullets. Neither is consumed, so one of either lasts forever. Bare hands also work for glass, at a cost.
- Suture Needle (single-use), the purpose-built tool. Found in pharmacies, hospitals, doctor offices, and ambulances.
- OR Needle + Thread, the household alternative. The needle is reusable and the thread depletes. Found in sewing kits, kitchens, clothing stores.
- Forceps (optional). In Build 42 the item is called Forceps; its internal ID is still
Base.SutureNeedleHolder, which is why older guides call it a Suture Needle Holder. It is not consumed, it removes glass and bullets, and carrying it makes stitching cheaper. A forged version can be made at Blacksmithing 4. - Disinfectant (optional): Bottle of Disinfectant, alcohol, or a spirit. Note that disinfecting adds pain in proportion to how strong the alcohol is.
- Bandage, applied over the stitch. A clean or sterilized bandage lowers the chance of wound infection, and a bandage on a stitch increases the healing rate.
Step-by-Step Treatment
- Get somewhere safe. Every one of these actions roots you in place.
- Open the Health panel (hotkey
H) and read the body part before bandaging anything. - If it shows Lodged Glass Shards or Lodged Bullet, right-click and remove it. Use tweezers or forceps if you have them.
- Disinfect if you have something to disinfect with. It stings, and it lowers the chance of the wound becoming infected.
- Right-click the deep wound and Stitch, with either a Suture Needle or a Needle plus Thread.
- Bandage the stitched wound, sterilized bandage preferred.
- Replace the bandage whenever it goes dirty. A dirty bandage is worse than no bandage for infection risk.
- Remove the stitches once the wound has settled (see below).
What does my Health panel say?
| The panel shows | Do this |
|---|---|
| Deep Wound | Disinfect if you can, then stitch, then bandage. |
| Deep Wound + Lodged Glass Shards | Remove the glass first. The Stitch option will not appear until you do. |
| Lodged Bullet | Remove it with tweezers or forceps, then treat the resulting deep wound normally. |
| Stitched | Bandage it and leave it. At First Aid 7+ the panel tells you when it is Good to come out. |
| Infected | Ordinary bacterial wound infection. Clean bandages, disinfect. This is not the Knox Infection. |
| Lacerated | Bandage it. You cannot stitch a laceration, the option only exists for deep wounds. If it came from a zombie, see infection. |
| Bitten | Bandage to stop the health loss, then read what a bite actually means. This one is the serious one. |
Tool Comparison: What Actually Reduces the Pain?
This is simpler than most guides make it. The stitching action adds a fixed amount of pain, and having either a Suture Needle or Forceps in your inventory halves it. They do not stack, so carrying both gives you exactly the same result as carrying one. Your First Aid level then subtracts one point of pain per level on top.
| Setup | Pain added | Speed | Consumes |
|---|---|---|---|
| Suture Needle (forceps make no further difference) | 10, minus your First Aid level | Faster | 1 suture needle |
| Needle + Thread, forceps carried | 10, minus your First Aid level | Faster | Some thread |
| Needle + Thread, no forceps | 20, minus your First Aid level | Baseline | Some thread |
| Removing the stitches later | 5, minus your First Aid level | Faster if forceps carried | Nothing |
Two consequences worth knowing. At high First Aid the pain subtraction can wipe the cost out entirely. And the stitching action itself can give you a wound infection, on a roll that depends only on your First Aid level: it is roughly a 1 in 5 chance at level 0, around 1 in 15 at level 4, and about 1 in 30 at level 10. Levelling First Aid is the real upgrade here, not the loot.
If your character is Hemophobic, stitching, removing glass, and removing a bullet each spike panic hard. Do them somewhere you can afford to be panicking.
Healing Time, and Can It Heal Without Stitches?
It can. Keeping a deep wound bandaged without ever stitching it will let it heal, but it takes on the order of a month of in-game time. Through all of that it bleeds for a long stretch, the bandage keeps going dirty, and you have to keep eating to offset the health drain. That is a survival situation, not a plan.
Stitched and bandaged, it closes in a small number of in-game days instead. Pain stays elevated until it does, which affects movement and combat. Sleeping and being well fed speed up recovery generally; being hungry, thirsty, or sick slows it. The Fast Healer trait reduces the severity of fresh injuries rather than accelerating an existing one.
One myth worth killing: an ordinary wound infection does not slow your healing. It increases that wound's pain slightly and nothing else. And caffeine pills, which older guides still call vitamins, only reduce fatigue. They are not a healing drug.
Removing the Stitches
The game lets you remove stitches whenever you like, so nothing forces you to wait and nothing punishes you for waiting. The useful signal is level-gated: at First Aid 7 or higher the Health panel annotates a stitched body part as Good once the stitch has been in long enough, and tells you it needs more time before that. Below level 7 you get no annotation at all, so go by the wound: wait until the bleeding has stopped and the body part is no longer draining health.
A detail that rewards skill: the stitch gets a head start proportional to your First Aid level at the moment you make it. A stitch put in by a trained character is ready to come out sooner than one put in by a beginner. Removing them grants First Aid XP, the same as putting them in, so it is a free skill drip either way.
Common Mistakes
| Mistake | Consequence |
|---|---|
| Bandaging before reading the panel | A bandage hides the Lodged Glass or Lodged Bullet line. The object is still in you and still bleeding you. |
| Hunting for a Stitch option that is not there | Glass in the wound removes the option entirely. Take the shard out first. |
| Digging glass out with bare hands when you own tweezers | Twice the action time and an extra 30 pain for nothing. |
| Carrying a suture needle and forceps expecting them to stack | They do not. Either one alone gives the same reduced pain and time. |
| Bandaging and never stitching | It will heal, in about a month of in-game time, while bleeding and draining health the whole way. |
| Reading Infected as zombie infection | Wrong panic. It is bacterial, it is minor, and the Knox Infection never appears in the panel at all. |
| Leaving a dirty bandage on | Worse than a clean one by a wide margin. It actively raises wound infection risk. |
Infected Is Not the Knox Infection
These are two completely different things and confusing them is the single most common panic on this topic.
Infected on a body part is an ordinary bacterial wound infection. You get it from not bandaging in time, from leaving a dirty bandage on, or from the stitching roll above. It slightly increases that wound's pain and does not penalize your health, your healing rate, or your physical ability any further. Clean bandages and disinfectant deal with it.
The Knox Infection is never displayed in the Health panel at all. Under default settings a zombie bite is a guaranteed vector, while zombie lacerations and scratches each carry a chance of it. Symptoms usually show within a day: overheating, sickness, constant stress regardless of your traits, and health loss that accelerates. It ends in death and reanimation, on average within about three days.
A deep wound is not on that list. Glass, falls, vehicles, axes, and pulling foreign objects out are what cause deep wounds. If you have a deep wound and a zombie-inflicted injury at the same time, treat them as two separate problems: see bites and the sickness and infection guide.
