Cuts And Grazes

Overview

A cut is a break in the skin, usually made by something sharp like a knife, a piece of glass or the edge of a tin. A graze (also called a scrape or abrasion) is when the top layer of skin has been rubbed or scraped away, often after a fall onto a rough surface like concrete or gravel. Both are types of wound, which simply means damage to the skin. Most are small and can be looked after at home, but some need a doctor or nurse to check them.

Very common. Almost everyone gets a cut or graze at some point, and they are one of the most frequent reasons people seek minor first aid advice.

Anyone can get a cut or graze, but they are especially common in children who are running, climbing and playing sport, people who work with tools or machinery, keen gardeners and cooks, and older adults whose skin is thinner and bruise or tear more easily.

Symptoms

Common symptoms

• Bleeding from the damaged area, which is usually small and stops within a few minutes of firm pressure
• Pain, stinging or soreness around the wound, especially when it is cleaned or touched
• The skin edges may look slightly apart in a deeper cut
• A graze often looks red and raw, sometimes with tiny specks of dirt or grit in it
• Mild swelling or bruising around the area for a day or two

Symptoms in children

• Crying or distress, which is often brief once the wound is cleaned and covered
• Grazes on knees, elbows, hands and chin after falls are very common
• Children may pick at scabs or plasters, which can slow healing
• Young children may not be able to tell you how much it hurts, so watch for changes in behaviour or feeding

Symptoms in older adults

• Skin tears more easily and may bleed more because skin becomes thinner with age
• Bleeding may take longer to stop in people taking blood-thinning medicine
• Healing can be slower, so wounds may need a little more time and care
• Bruising around the wound may be more noticeable

Causes

Main causes

• Falling onto a rough surface such as concrete, gravel or tarmac, which scrapes the skin
• Handling sharp objects like knives, scissors, broken glass, tin lids or tools
• Sport and play injuries, including collisions and sliding tackles
• Bites and scratches from pets or other animals
• Bumping into furniture or sharp edges at home
• Workplace accidents involving machinery, blades or sharp materials

Risk factors

• Being a young child or a teenager, when falls and scrapes are part of everyday life
• Taking part in contact sports or cycling without protective gear
• Working in construction, catering, gardening or other jobs with sharp tools
• Older age, because skin gets thinner and more fragile
• Conditions or medicines that affect blood clotting or the immune system
• Diabetes or poor circulation, which can slow healing and raise infection risk
• Drinking alcohol or using substances, which increases the chance of falls and accidents
• Not being up to date with tetanus vaccination

When to see a doctor

See a doctor urgently if:

• Bleeding that restarts or will not stop after 10 minutes of firm pressure
• Signs of infection such as spreading redness, swelling, pus, or a temperature
• A gaping wound, or one that might need stitches or glue
• Any animal or human bite, especially on the hand or face
• Something stuck in the wound that you cannot wash out
• Numbness, weakness, or trouble moving the area below the wound
• A wound that is very dirty or caused by something rusty, sharp and dirty, or by soil — you may need a tetanus check

Book a routine appointment if:

• A wound that seems to be healing but is still sore or weeping after several days
• A scar that is becoming raised, thick or itchy
• Repeated cuts or grazes that suggest a balance, eyesight or mobility problem
• A wound on a foot in someone with diabetes, even if it looks minor

Diagnosis

A doctor or nurse usually diagnoses a cut or graze simply by looking at it and asking how it happened. They will check how deep it is, whether the edges sit together, whether there is dirt or an object inside, and whether feeling and movement are normal in the area. They may also ask about your general health, medicines you take, and when you last had a tetanus vaccination.

Tests that may be done

• Usually no tests are needed
• Checking tetanus vaccination history, and offering a booster if it is not up to date
• An X-ray if there might be glass, metal or another object inside the wound
• A wound swab, only if the wound looks infected
• Blood tests in rare cases, if healing is poor or infection is suspected to have spread

What to expect at your appointment

The appointment is usually quick and gentle. The doctor or nurse may clean the wound, remove any grit, and decide whether it needs closing. You can ask questions at any point, and it is fine to say if you feel nervous about the cleaning or stitching.

Treatment

Most cuts and grazes are treated with good first aid at home, and the body does the rest. The aim is to stop any bleeding, clean the wound so dirt does not cause infection, and keep it covered while the skin knits back together. Deeper or dirtier wounds may need a doctor or nurse to clean and close them.

Self-care at home

• Wash your hands thoroughly before touching the wound
• Press firmly on the wound with a clean cloth or sterile gauze for up to 10 minutes to stop the bleeding — do not keep lifting it to peek
• Rinse the wound under clean running water, or use a clean damp cloth to wipe away grit and dirt
• Gently pat the skin around the wound dry, then cover it with a plaster or a low-stick dressing
• Change the dressing daily, or sooner if it becomes wet or dirty
• Keep the wound clean and dry, and avoid picking at scabs, as they protect new skin underneath
• If the wound is on a hand or arm, you can raise it above heart level to help slow bleeding and reduce swelling
• Take simple pain relief if needed, and ask a pharmacist if you are unsure what suits you

Medical treatments

A healthcare professional may clean the wound more thoroughly, remove grit or small objects, and close the wound with stitches, skin glue or staples if it is gaping. They will dress it and explain how to care for it at home, and when to come back to have stitches or staples removed. Antibiotic medicine may be offered if a wound is infected or at high risk of infection, and a tetanus booster may be given if your protection is out of date. If a wound is infected, the professional will explain what to look out for as it heals.

When is surgery considered?

Surgery is rarely needed for a cut or graze. It may be considered for very deep wounds, wounds with an object that cannot be removed easily, or damage to nerves, tendons or blood vessels, in which case a specialist team would assess and repair the wound under proper anaesthesia.

Living with this condition

Most people carry on with normal life while a cut or graze heals. Keep the wound covered for the first few days, change the dressing regularly, and wash around it gently rather than scrubbing it. It is fine to shower, but try not to soak the wound in a bath or pool until it has closed.

Lifestyle tips

• Wear gloves for gardening, DIY and handling sharp or dirty objects
• Wear shoes outdoors, especially on rough ground or building sites
• Keep a small first aid kit at home and in the car with plasters, gauze and a clean cloth
• Use protective gear for sport, such as knee pads for skating or a helmet for cycling
• Check your feet regularly if you have diabetes or poor circulation
• Keep sharp knives and tools out of reach of young children

Diet and exercise

Eating well supports healing: include protein such as beans, eggs, fish or chicken, plus fruit and vegetables for vitamins, and drink enough water. Gentle exercise is usually fine and helps you feel well, but protect the wound and avoid activities that could reopen it until it has closed. Smoking slows healing, so it is worth asking for help to stop if you smoke.

Mental health and emotional wellbeing

Most cuts and grazes are quickly forgotten, but a painful or visible wound, a scar, or an injury from an accident can leave you feeling shaken or worried. That is understandable, and it usually settles as the wound heals. If the injury came from self-harm, or you are struggling with low mood or anxiety, please tell a doctor or nurse — you deserve support, and help is available. If you ever feel unsafe or in crisis, contact your local emergency number or a crisis line in your area straight away.

Prevention

You cannot prevent every bump and scrape, but you can greatly lower the chance of cuts and grazes. Most prevention is simple: keep sharp things safely stored, wear gloves and shoes when the ground or the task is risky, use protective gear for sport, and keep a well-stocked first aid kit so you can act quickly when accidents happen.

Vaccines

Tetanus vaccination is the key protection linked to cuts and grazes. In the UK, tetanus cover is part of the routine childhood immunisation schedule, with boosters at school age. Adults may need a booster if they have a dirty wound and their cover is not up to date. Ask your doctor or practice nurse to check your record — they can tell you whether you need a booster.

Complications

If left untreated

• Infection, which can cause spreading redness, swelling, pain, pus and a temperature
• A wound that heals slowly or reopens
• A more noticeable scar, including raised or thickened scars
• Tetanus, a rare but serious infection linked to dirty wounds, in people who are not vaccinated
• Rarely, damage to nerves, tendons or blood vessels from a deep wound

Long-term outlook

The outlook for most cuts and grazes is very good. Small wounds usually close within a few days and are fully healed in one to two weeks, sometimes with a faint mark that fades over months. Deeper wounds take a little longer, and good cleaning, covering and hygiene give you the best chance of a neat, trouble-free heal. If anything worries you as it heals, your doctor or pharmacist can help.
